Agilent 34410A/11A/L4411A 6½ Digit Multimeter Programmer's Reference This Help file contains reference information to help you program the Agilent 34410A/11A/L4411A over a remote interface using the SCPI programming language.

Introduction to the SCPI Language SCPI (Standard Commands for Programmable Instruments) is an ASCII-based instrument command language designed for test and measurement instruments. SCPI commands are based on a hierarchical structure, also known as a tree system. In this system, associated commands are grouped together under a common node or root, thus forming subsystems. A portion of the SENSe subsystem is shown below to illustrate the tree system.
Syntax Conventions The format used to show commands is illustrated below: VOLTage:DC:RANGe {|MIN|MAX|DEF} The command syntax shows most commands (and some parameters) as a mixture of upper- and lower-case letters. The upper-case letters indicate the abbreviated spelling for the command. For shorter program lines, you can send the abbreviated form. For better program readability, you can send the long form. For example, in the above syntax statement, VOLT and VOLTAGE are both acceptable forms.
Command Separators A colon ( : ) is used to separate a command keyword from a lower-level keyword. You must insert a blank space to separate a parameter from a command keyword. If a command requires more than one parameter, you must separate adjacent parameters using a comma as shown below: CONF:VOLT:DC 10,0.003 A semicolon ( ; ) is used to separate commands within the same subsystem, and can also minimize typing. For example, sending the following command string: TRIG:SOUR EXT; COUNT 10 ...
Using the MIN, MAX, and DEF Parameters For many commands, you can substitute "MIN" or "MAX" in place of a parameter. In some cases you may also substitute "DEF". For example, consider the following command: VOLTage:DC:RANGe {|MIN|MAX|DEF} Instead of selecting a specific value for the parameter, you can substitute MIN to set the range to its minimum value, MAX to set the range to its maximum value, or DEF to set the range to its default value.
Querying Parameter Settings You can query the current value of most parameters by adding a question mark ( ? ) to the command.
SCPI Command Terminators A command string sent to the instrument must terminate with a () character. The IEEE-488 EOI (End-Or-Identify) message is interpreted as a character and can be used to terminate a command string in place of a character. A followed by a is also accepted. Command string termination will always reset the current SCPI command path to the root level.
IEEE-488.2 Common Commands The IEEE-488.2 standard defines a set of common commands that perform functions such as reset, self-test, and status operations. Common commands always begin with an asterisk ( * ), are three characters in length, and may include one or more parameters. The command keyword is separated from the first parameter by a blank space.
SCPI Parameter Types The SCPI language defines several data formats to be used in program messages and response messages. Numeric Parameters Commands that require numeric parameters will accept all commonly used decimal representations of numbers including optional signs, decimal points, and scientific notation. Special values for numeric parameters such as MIN, MAX, and DEF are also accepted. You can also send engineering unit suffixes with numeric parameters (e.g., M, k, m, or u).
condition, the instrument will accept "ON" or "1". When you query a boolean setting, the instrument will always return "0" or "1". The following command requires a boolean parameter: VOLTage:DC:IMPedance:AUTO {OFF|0|ON|1} ASCII String Parameters String parameters can contain virtually any set of ASCII characters. A string must begin and end with matching quotes; either with a single quote or a double quote.
Using Device Clear Device Clear is an IEEE-488 low-level bus message that you can use to return the instrument to a responsive state. Different programming languages and IEEE-488 interface cards provide access to this capability through their own unique commands. The status registers, the error queue, and all configuration states are left unchanged when a Device Clear message is received. Device Clear performs the following actions: If a measurement is in progress, it is aborted.
Commands by Subsystem Other Commands CALCulate Subsystem CALibration Subsystem CONFigure Subsystem DATA Subsystem DISPlay Subsystem FETCh Subsystem FORMat Subsystem IEEE-488.
ABORt Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax ABORt
Description This command aborts a measurement in progress.
Remarks This command may be useful to abort a measurement when the instrument is waiting for a trigger, for a long measurement (for example, 100 plc), or for a long series of timed measurements. The command will abort a measurement in progress and stop, returning the instrument to the trigger idle state. The *RST command will abort a measurement and set all measurement parameters to their factory settings. The Instrument Preset (SYSTem:PRESet command) does the same.
Example The following command aborts the measurement in progress.
See Also *RST SYSTem:PRESet
INITiate[:IMMediate] Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax INITiate[:IMMediate]
Description This command changes the state of the triggering system from the "idle" state to the "wait-for-trigger" state. Measurements will begin when the specified trigger conditions are satisfied following the receipt of the INITiate command. Note that the INITiate command also clears the previous set of readings from memory.
Remarks Storing readings in memory using the INITiate command is faster than sending readings to the output buffer using the READ? command. The INITiate command is also an "overlapped" command. This means that after executing the INITiate command, you can send other commands that do not affect the measurements. The 34410A provides volatile reading memory for up to 50,000 readings. The 34411A/L4411A provides volatile reading memory for up to 1,000,000 readings.
Example The following program segment shows how to use the INITiate command with the CONFigure and FETCh? commands. The INITiate command places the instrument in the "wait-for-trigger" state, triggers a measurement when the rear-panel Ext Trig Inputline is pulsed (low by default), and then sends the readings to memory. The FETCh? command transfers the readings from memory to the instrument's output buffer. CONF:VOLT:DC 10,0.003 TRIG:SOUR EXT INIT FETC? Typical Response: +4.

OUTPut:TRIGger:SLOPe Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax OUTPut:TRIGger:SLOPe OUTPut:TRIGger:SLOPe?
Description This command selects the slope of the voltmeter complete output signal on the rear-panel VM Comp BNC connector. The default is NEG.
Parameters Name Type Range of Values Default Value Discrete {POSitive|NEGative} NEG
Remarks See VM Comp Output for further information. The instrument selects a negative slope after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns either "POS" or "NEG".
Examples The following command sets the VM Comp slope to negative. OUTP:TRIG:SLOP NEG The following query returns currently selected slope.
See Also VM Comp Output
R? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax R? []
Description This command reads and erases readings from volatile memory up to the specified . The readings are erased from memory starting with the oldest (not the most recent) reading first. The purpose of this command is to allow you to periodically remove readings from memory that would normally cause reading memory to overflow.
Parameters Name Type Range of Values Default Value Numeric Maximum number of readings to be read and erased from memory.
Remarks This command differs from the DATA:REMove? command in that R? will read and erase whatever readings are available in memory, up to the specified . On the other hand, DATA:REMove will error if the requested number of readings are not in memory when the command is sent. You can read memory at any time using the R? command, even during a measurement. The 34410A provides volatile reading memory for up to 50,000 readings.
Return Format The command returns a series of readings in Definite-Length Block format. The syntax is a pound sign (#) followed by a non-zero digit representing the number of digits in the decimal integer to follow. This digit is followed by a decimal integer indicating the number of 8-bit data bytes to follow. This is followed by a block of data containing the specified number of bytes. The reading format is determined by the FORMat Subsystem commands.
Example This command reads the two oldest readings and erases them from memory. R? 2 Typical Response: #231+2.87536000E-04,+3.
See Also DATA:REMove? FETCh? FORMat:BORDer FORMat[:DATA]
READ? Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax READ?
Description This command changes the instrument's triggering system from the "idle" state to the "wait-for-trigger" state. Measurements will begin when the specified trigger conditions are satisfied following the receipt of the READ? command. Readings are then sent immediately to volatile memory and the instrument's output buffer.
Remarks Sending the READ? command is similar to sending the INITiate command followed immediately by the FETCh? command. The 34410A provides volatile reading memory for up to 50,000 readings. The 34411A/L4411A provides volatile reading memory for up to 1,000,000 readings. If memory overflows, the new readings will overwrite the first (oldest) readings stored; the most recent readings are always preserved.
Return Format The command sends readings directly to reading memory and the instrument's output buffer. The readings are returned in ASCII format.
Examples The following program segment shows how to use the READ? command with the CONFigure command. The READ? command places the instrument in the "wait-for-trigger" state, triggers a measurement when the rear-panel Ext Trig Inputline is pulsed (low by default), sends the readings to memory, and then transfers the readings to the instrument output buffer. CONF:VOLT:DC 10,0.003 TRIG:SOUR EXT READ? Typical Response: +4.
See Also FETCh? FORMat:BORDer FORMat[:DATA] INITiate[:IMMediate]
ROUTe:TERMinals? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax ROUTe:TERMinals?
Description This command queries the 34410A/34411A multimeter to determine whether the front or rear input terminals are selected (via the front/rear switch on the front panel). The front/rear switch should not be toggled with active signals on the terminals. This switch is not intended to be used in this way, and may be damaged by high voltages or currents, possibly compromising the instrument's safety features.
Remarks The front/rear switch is not programmable. This query reports the position of the switch, but cannot change it.
Return Format The query returns the current state of the front/rear switch: "FRON" or "REAR", indicating which set of terminals are in use.
Example The following query returns the current state of the 34410A/34411A front/rear switch (the set of input terminals selected).
UNIT:TEMPerature Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax UNIT:TEMPerature UNIT:TEMPerature?
Description This command selects the units (°C, °F, or Kelvins) to be used for temperature measurements. The 34410A/11A/L4411A uses the selected unit for temperature measurements regardless of the transducer selection (thermistor, or 2-wire or 4-wire RTD).
Parameters Name Type Range of Values Default Value Discrete {C|F|K} Required parameter.
Remarks The command also accepts "CEL" or "FAR" for the units parameter, but the query returns "C" or "F". The temperature unit selection is stored in volatile memory. The selection is set to °C after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns "C", "F", or "K".
Examples The following command sets the temperature units to °F. UNIT:TEMP F The following query returns the temperature unit selected.

CALCulate:AVERage:SDEViation?
CALCulate:FUNCtion Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax CALCulate:FUNCtion {NULL | DB | DBM | AVERage | LIMit} CALCulate:FUNCtion?
Description This command selects the calculation function to be used. The default function is NULL. The null function provided in this command is for compatibility with the 34401A 6½ Digit Multimeter. For the 34410A, 34411A,L4411A it is recommended that you use the individual (null per function) null commands found in the [SENSe:] subsystem, rather than the null function provided by the CALCulate:NULL:OFFSet command. Avoid using both types of nulls, as unexpected results may occur (they are additive).
Remarks Send CALCulate:FUNCtion AVERage to enable statistics. When statistics are enabled, the average (mean), minimum, maximum, peak-to-peak, count, and standard deviation values are calculated and carried in the statistical data registers, available to be read with the statistics (CALCulate:AVERage) commands such as CALCulate:AVERage:AVERage? and CALCulate:AVERage:SDEViation?. The CALCulate subsystem (math operations) must be enabled using the CALCulate:STATe command.
Return Format The query returns the currently selected function: NULL, DB, DBM, AVER, or LIM.
Examples The following command sets the function to be calculated to DBM. CALC:FUNC DBM The following query returns the currently enabled calculation function.
See Also CALCulate:STATe
CALCulate:STATe Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax CALCulate[:STATe] {OFF | ON} CALCulate:STATe?
Description This command turns the CALCulate subsystem, and thus the selected calculation function, on or off.
Remarks The calculation function to be used is selected using the CALCulate:FUNCtion command. CALCulate:STATe is set to OFF when the measurement function is changed. When CALCulate:STATe:ON is sent the math registers for limits, statistics, dB relative value, and the value set by CALCulate:NULL:OFFSet are cleared. This also occurs when CALCulate:FUNCtion is sent with CALCulate:STATe previously set to ON. Note that the dBm reference resistance value is not cleared in either case.
Return Format The query returns the current calculation state: "0" (OFF) or "1" (ON).
Example The following command sets the calculation state to "ON". CALC:STAT ON The following query returns the current calculation state.

CALibration[:ALL]? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax CALibration[:ALL]?
Description This command performs a calibration of the multimeter using the specified calibration value (CALibration:VALue command). Before you can calibrate the instrument, you must unsecure it by entering the correct security code. For a more detailed discussion of the calibration procedures, see the Agilent 34410A/11A/L4411A Service Guide. Please refer to the Service Guide before attempting to calibrate the instrument.
Remarks If a calibration fails, "+1" is returned and an error is stored in the error queue. For a complete listing of the error messages related to calibration failures, see SCPI Error Messages. This command increments the calibration count on the 34410A, 34411A, or L4411A (see CALibration:COUNt? command).
Return Format The command returns "+0" (calibration passed) or "+1" (calibration failed).
Example The following command performs a calibration and returns a pass/fail indication.

CALibration:COUNt? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax CALibration:COUNt?
Description This command queries the instrument to determine how many calibrations have been performed. Note that your instrument was calibrated before it left the factory. When you receive your instrument, be sure to read the count to determine the initial values. For a more detailed discussion of the calibration procedures, see the Agilent 34410A/11A/L4411A Service Guide. Please refer to the Service Guide before attempting to calibrate the instrument.
Remarks The calibration counts increment up to a maximum of over four billion (232 - 1) after which they roll over to "0". Since the value increments by one for each calibration point, a complete calibration may increase the value by many counts. However, it is unlikely that the count will ever roll over due to the high maximum. The calibration count is incremented by the CALibration? command. You can read the calibration count whether the instrument is secured or unsecured.
Return Format The command returns the calibration count indicating how many calibrations have been performed.
Example The following command returns the calibration count.

Syntax CALibration:LFRequency CALibration:LFRequency?
Description The query returns the power-line reference frequency currently used by the 34410A/11A/L4411A analog-to-digital converter (50 or 60 Hz). When you apply power to the instrument, the instrument automatically detects the power-line frequency and uses this value to determine the integration time used. The command form allows you to override automatic detection and set either 50 or 60 Hz.
Parameters Name Type Range of Values Default Value Numeric 50 (50 Hz or 400 Hz) 60 (60 Hz) Defaults to sensed line frequency
Remarks The instrument multiplies the period of the reference frequency by the specified number of power line cycles ([SENSe:]:NPLC commands) to determine the actual integration time. The reference frequency setting is stored in volatile memory and will be lost when power is turned off. The instrument automatically detects the power-line frequency (50 Hz, 60 Hz, or 400 Hz) at power-on.
Return Format The query returns "+50" (for 50 Hz or 400 Hz) or "+60" (for 60 Hz) indicating the present reference frequency setting.
Example The following command sets the reference frequency to 60 Hz (overriding automatic detection). CAL:LFR 60 The following command returns the reference frequency setting.

CONFigure Subsystem Introduction The CONFigure command provides the most concise way to program the instrument for measurements. When you execute this command, the instrument uses default values for the requested measurement configuration (like the MEASure? command). However, the measurement is not automatically started and you can change some measurement attributes before actually initiating the measurement. This allows you to incrementally change the instrument's configuration from the default conditions.
Command Summary CONFigure:CAPacitance CONFigure:CONTinuity CONFigure:CURRent:AC CONFigure:CURRent[:DC] CONFigure:DIODe CONFigure:FREQuency CONFigure:FRESistance CONFigure:PERiod CONFigure:RESistance CONFigure:TEMPerature CONFigure[:VOLTage]:AC CONFigure[:VOLTage][:DC] CONFigure?
Default Settings for the CONFigure Command With the CONFigure command, you can select the function, range, and resolution all in one command. All other measurement parameters are set to their default values as shown below.
The AC Filter, Autozero, and Null State parameters can be set individually for each applicable measurement function. However, in each case, the defaults are as listed in the table above. Input Impedance applies only to dc voltage measurements.
Using the CONFigure Command The following program segment shows how to use the CONFigure command with the READ? command to make an externally-triggered measurement. The CONFigure command configures the instrument for dc voltage measurements. Note that the CONFigure command does not place the instrument in the "waitfor-trigger" state.
The following program segment configures the instrument for 2-wire resistance measurements, triggers the meter to make one measurement using the INITiate, and then stores the reading in memory. The 10 kΩ range is selected with 100Ω resolution. CONF:RES 10000,100 INIT FETC? Typical Response: +5.
CONFigure:CAPacitance Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax CONFigure:CAPacitance [{|AUTO|MIN|MAX|DEF} [, {|MIN|MAX|DEF}]]
Description First, this command resets all capacitance measurement parameters and trigger parameters to their default values. Then, it configures the meter for capacitance measurements but does not initiate the measurement. The CONFigure command does not place the instrument in the "wait-fortrigger" state. Use the INITiate or READ? command in conjunction with CONFigure to place the instrument in the "wait-for-trigger" state.
Parameters Name Type Range of Values Default Value Desired range in F (farads): Numeric Numeric 1 nF (MIN) 10 nF 100 nF 1 µF 10 µF (MAX) AUTO (autorange) (DEF) Desired resolution in F (farads). AUTO Fixed at 4½ digits.
Remarks The parameter is optional, and is in fact ignored. The resolution is actually fixed at 4½ digits. You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal.
Examples The following program segment configures the instrument for capacitance measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer. The default range (AUTO) and resolution (4½ digits) are used for the measurement. CONF:CAP READ? Typical Response: +0.

CONFigure:CONTinuity Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax CONFigure:CONTinuity
Description First, this command resets all continuity measurement parameters and trigger parameters to their default values. Then, it configures the meter for continuity measurements but does not initiate a measurement. Continuity is a special type of fixed-range 2-wire resistance measurement. This command presets the meter to a fixed range and resolution, and then configures for continuity tests. However, it does not initiate the test.
Remarks The range and resolution are fixed for continuity tests. The range is 1 kΩ (a 2-wire resistance measurement). The meter beeps (even if beep is disabled) for each measurement that is less than or equal to the continuity threshold (≤10 Ω), and the actual resistance reading is displayed on the front panel. From 10 Ω to 1.2 kΩ the meter displays the actual resistance reading with no beep. If the reading exceeds 1.2 kΩ, the meter displays "OPEN" on the front panel (no beep).
Examples The following program segment configures the instrument for continuity measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer. CONF:CONT READ? Typical Response: +1.

Description First, this command resets all ac current measurement parameters and trigger parameters to their default values. Then, it configures the meter for ac current measurements but does not initiate a measurement. The CONFigure command does not place the instrument in the "wait-fortrigger" state. Use the INITiate or READ? command in conjunction with CONFigure to place the instrument in the "wait-for-trigger" state.
Parameters Name Type Range of Values Default Value Desired range in amps: Numeric Numeric 100 µA (MIN) 1 mA 10 mA 100 mA 1A 3 A (MAX) AUTO (autorange) Desired resolution in amps. AUTO (autorange) Fixed at 6½ digits.
Remarks The parameter is optional, and is in fact ignored. The resolution is actually fixed at 6½ digits. You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal.
Examples The following program segment configures the instrument for ac current measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer. The default range (autorange) and resolution (fixed at 6½ digits) are used for the measurement. CONF:CURR:AC READ? Typical Response: +8.

Remarks You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal. For faster measurements, use manual ranging on each measurement (some additional time is required for autoranging since the instrument has to make a range selection).
Examples The following program segment configures the instrument for dc current measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer. The default range (autorange) and resolution (1 PLC) are used for the measurement. CONF:CURR:DC READ?

Remarks Frequency is measured on ac voltage signals. Thus, the proper ac voltage range should be set first using the [SENSe:]FREQuency:VOLTage:RANGe[:UPPer] command. The voltage range should be 0.1 volts or greater for more accurate frequency measurements. The parameter is required only to specify the measurement resolution parameter. Therefore, it is not necessary to send a new command for each new frequency to be measured.
Examples The following program segment configures the instrument for frequency measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer.

Remarks You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal. For faster measurements, use manual ranging on each measurement (some additional time is required for autoranging since the instrument has to make a range selection).
Examples The following program segment configures the meter for a 4-wire resistance measurement. The READ? command places the meter in the "wait-fortrigger" state, initiates a trigger, and then sends the reading to memory and the instrument output buffer.

Remarks Period is measured on ac voltage signals. Thus, the proper ac voltage range should be set first using the [SENSe:]PERiod:VOLTage:RANGe[:UPPer] command. The voltage range should be 0.1 volts or greater for more accurate period measurements. The parameter is required only to specify the measurement resolution parameter. Therefore, it is not necessary to send a new command for each new period to be measured.
Examples The following program segment configures the instrument for period measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer.

Use the INITiate or READ? command in conjunction with CONFigure to place the instrument in the "wait-for-trigger" state.
Parameters Name Type Range of Values Default Value Desired range in ohms: Numeric Numeric 100Ω (MIN) 1 kΩ 10 kΩ 100 kΩ 1 MΩ 10 MΩ 100 MΩ 1 GΩ (MAX) AUTO (autorange) Desired resolution in ohms (see Resolution Table or Range, Resolution, and NPLC for more information). AUTO (autorange) 0.
Remarks You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal. For faster measurements, use manual ranging on each measurement (some additional time is required for autoranging since the instrument has to make a range selection).
Examples The following program segment configures the instrument for 2-wire resistance measurements. The READ? command places the instrument in the "wait-for-trigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer. The default range (autorange) and resolution (1 PLC) are used for the measurement. CONF:RES READ?

Description First, this command resets all temperature measurement parameters and trigger parameters to their default values. Then, it configures the meter for temperature measurements but does not initiate the measurement. The CONFigure command does not place the instrument in the "wait-fortrigger" state. Use the INITiate or READ? command in conjunction with CONFigure to place the instrument in the "wait-for-trigger" state.
Parameters Name Type Discrete Range of Values Default Value {FRTD|RTD|FTHermistor|THERmistor} Required paramete DEF sets FRTD For THER: {2252|5000|10000} Required paramete DEF sets 5000 (2wire) {2252|5000|10000} Required paramete DEF sets 5000 (4wire) {85} Required paramete DEF sets 85 (2wire) {85} Required paramete DEF sets 85 (4wire) For FTH: Discrete For RTD: For FRTD: Numeric Desired resolution in the currently selected units (°C, °F, or K).
Remarks For temperature measurements, the instrument internally selects the range−you cannot select the range to be used. The range ("1" is the only allowed value) is used only in conjunction with resolution to determine NPLC. The range ("1") and parameters are optional. However, if you specify , you must also specify "1" as the implied range parameter (see syntax above). For example: CONF:TEMP THER,5000,1,0.1 specifies range = 1 and resolution = 0.
Examples The following program segment configures the instrument for 5 kΩ, 2-wire thermistor measurements. The INITiate command places the instrument in the "wait-for-trigger" state, triggers a measurement, and stores the reading in memory. The FETCh? command transfers the reading from reading memory to the instrument output buffer. This 2-wire measurement is made with 0.1 °C resolution (assumes default temperature units). CONF:TEMP THER,5000,1,0.1 INIT FETC? Typical Response: +2.

Description First, this command resets all ac voltage measurement parameters and trigger parameters to their default values. Then, it configures the meter for ac voltage measurements but does not initiate the measurement. The maximum range parameter is 1000 V, which is set by MAX. However, the SAFETY LIMIT on the front and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform dependent. A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is safe.
Parameters Name Type Range of Values Default Value Desired range in volts: Numeric Numeric 100 mV (MIN) 1V 10 V 100 V 1000 V (MAX) AUTO (autorange) Desired resolution in volts. AUTO (autorange) Fixed at 6½ digits.
Remarks The parameter is optional, and is in fact ignored. The resolution is actually fixed at 6½ digits. All ranges use the digital ac measurement technique. You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal.
Examples The following program segment configures the instrument for ac voltage measurements. The READ? command places the instrument in the "wait-fortrigger" state, triggers a measurement, and then sends the reading to memory and the instrument output buffer. The default range (autorange) and resolution (fixed at 6½ digits) are used for the measurement. CONF:VOLT:AC READ?

DATA:COPY Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax DATA:COPY NVMEM, RDG_STORE
Description This command copies the readings in reading memory (RDG_STORE) into non-volatile memory (NVMEM). Non-volatile memory is not erased by a power-down cycle.
Remarks RDG_STORE is volatile, and the readings are lost on power-down unless the readings have been copied into non-volatile memory. For the 34410A, RDG_STORE can hold up to 50,000 readings, all of which are copied into non-volatile memory. The 34411A/L4411A increases RDG_STORE (volatile memory) space to 1,000,000 readings. However, non-volatile memory space remains fixed at 50,000 readings.
Examples The following command copies all readings (up to the first 50,000 for the 34411A/L4411A) from RDG_STORE into non-volatile memory.

Description This command transfers readings to the instrument's output buffer where you can read them into your computer. The readings are not erased from memory when you read them. You can send the command multiple times to retrieve the same data in reading memory.
Remarks The FETCh? command will wait until the measurement is complete to terminate. The 34410A provides volatile reading memory for up to 50,000 readings. The 34411A/L4411A provides volatile reading memory for up to 1,000,000 readings. If memory overflows, a status register bit is set and new readings will overwrite the first (oldest) readings stored. The most recent readings are always preserved.
Return Format The command transfers all readings from memory but does not erase them. The readings are returned in ASCII format.
Example The following program segment shows how to use the FETCh? command with the CONFigure and INITiate commands. The INITiate command places the instrument in the "wait-for-trigger" state, triggers a measurement when the rear-panel Ext Trig Inputline is pulsed (low by default), and then sends the readings to memory.

Syntax FORMat:BORDer {NORMal|SWAPped} FORMat:BORDer?
Description Used for binary block transfers only. This command selects the byte order for binary block transfers using the DATA:REMove? and R? commands.
Remarks In the NORMal byte order (default) the most-significant byte (MSB) of each data point is assumed first. In the SWAPped byte order the least-significant byte (LSB) of each data point is assumed first. Most PCs use the "swapped" byte order. The byte order setting is stored in non-volatile memory and does not change when power has been off. The default value will be restored after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns "NORM" or "SWAP".
Examples The following command enables the "swapped" byte order mode. FORM:BORD SWAP The following query returns the current byte order setting.

Description This command enables bits in the enable register for the Standard Event Register group. The selected bits are then reported to bit 5 of the Status Byte Register. For more information on the SCPI Status System for the Agilent 34410A/11A/L4411A, see Status System Introduction.
Parameters Name Type Range of Values Default Value Numeric A decimal value which corresponds to the binaryweighted sum of the bits in the register (see table below).
Remarks The following table lists the bit definitions for the Standard Event Register. Decimal Value Definition 0 Operation Complete 1 All commands prior to and including *OPC have been executed. 1 Not Used Not Used "0" is returned. 4 The instrument tried to read the output buffer but it was empty. Or, a new command line was received before a previous query has been read. Or, both the input and output buffers are full.
Use the parameter to specify which bits will be enabled. The decimal value specified corresponds to the binary-weighted sum of the bits you wish to enable in the register. For example, to enable bit 2 (decimal value = 4), bit 3 (decimal value = 8), and bit 7 (decimal value = 128), the corresponding decimal value would be 140 (4 + 8 + 128). You can use the *PSC command to control whether the Standard Event enable register is cleared at power on.
Return Format The query command reads the enable register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register. For example, if bit 3 (decimal value = 8) and bit 7 (decimal value = 128) are enabled, the query command will return "+136".
Examples The following command enables bit 4 (decimal value = 16) in the enable register. If an Execution Error occurs, this condition will be reported to the Status Byte Register (bit 5 will be set high). *ESE 16 The following query returns which bits are enabled in the register.

*RCL Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax *RCL {0|1|2|3|4}
Description This command recalls the instrument state stored in the specified storage location. You cannot recall the instrument state from a storage location that is empty or was deleted. When shipped from the factory, storage locations 1 through 4 are empty (location 0 has the power-on state). Use the *SAV command to store the current instrument state.
Remarks The instrument has five storage locations in non-volatile memory to store instrument states. The instrument uses location 0 to automatically hold the state of the instrument at power down. You can only recall a state from a location that contains a previously stored state. A Factory Reset (*RST command) or SYSTem:PRESet command does not affect the configurations stored in memory. Once a state is stored, it remains until it is overwritten or specifically deleted.
Example The following command recalls the instrument state previously stored in location 1.
See Also *SAV MEMory:STATe:DELete
*RST Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax *RST
Description This command resets the multimeter to the Factory configuration. See Factory Reset State for a complete listing of the instrument's Factory configuration.
Remarks This command does not affect any previously-stored instrument states (see *SAV command).

See Also SYSTem:PRESet
*SAV Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax *SAV {0|1|2|3|4}
Description This command stores (saves) the current instrument state in the specified storage location. Any state previously stored in the same location is overwritten (no error is generated). Use the *RCL command to recall a stored instrument state.
Remarks The instrument has five storage locations in non-volatile memory to store instrument states. The instrument uses location 0 to automatically hold the state of the instrument at power down. You can store the instrument state in location 1, 2, 3, or 4, but you can only recall a state from a location that contains a previously stored state. You can use location 0 to store a fifth instrument state, but keep in mind that location 0 is automatically overwritten when power is cycled.
Example The following command stores the current instrument state in location 1.
See Also *RCL MEMory:STATe:DELete
*SRE Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax *SRE *SRE?
Description This command enables bits in the enable register for the Status Byte Register group. Once enabled, the corresponding bits may generate a Request for Service (RQS) in the Status Byte. This RQS event may generate a "call back" to your application as a type of asynchronous interrupt. For more information on the SCPI Status System for the Agilent 34410A/11A/L4411A, see Status System Introduction.
Parameters Name Type Range of Values Default Value Numeric A decimal value which corresponds to the binaryweighted sum of the bits in the register (see table below).
Remarks The following table lists the bit definitions for the Status Byte Register. Bit Number Decimal Value Definition 0 Not Used 1 Always zero. 1 Not Used 2 Always zero. 4 One or more errors have been stored in the Error Queue. Use the SYSTem:ERRor? command to read and delete errors. 3 Questionable Data Summary 8 One or more bits are set in the Questionable Data Register (bits must be enabled, see STATus:QUEStionable:ENABle command).
Use the parameter to specify which bits will be enabled. The decimal value specified corresponds to the binary-weighted sum of the bits you wish to enable in the register. For example, to enable bit 3 (decimal value = 8) and bit 5 (decimal value = 32), the corresponding decimal value would be 40 (8 + 32). The *CLS (clear status) command will not clear the enable register but it does clear all bits in the event register.
Return Format The query command reads the enable register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register. For example, if bit 3 (decimal value = 8) and bit 5 (decimal value = 32) are enabled, the query command will return "+40".
Examples The following command enables bit 4 (decimal value = 16) in the enable register. *SRE 16 The following query returns which bits are enabled in the register.

*STB? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax *STB?
Description This command queries the condition register for the Status Byte Register group. This command is similar to a Serial Poll but it is processed like any other instrument command. This is a read-only register and the bits are not cleared when you read the register. For more information on the SCPI Status System for the Agilent 34410A/11A/L4411A, see Status System Introduction.
Remarks The following table lists the bit definitions for the Status Byte Register. Bit Number Decimal Value Definition 0 Not used 1 Always zero. 1 Not Used 2 Always zero. 4 One or more errors have been stored in the Error Queue. Use the SYSTem:ERRor? command to read and delete errors. 3 Questionable Data Summary 8 One or more bits are set in the Questionable Data Register (bits must be enabled, see STATus:QUEStionable:ENABle command).
This command returns the same results as a Serial Poll but the "Master Summary" bit (bit 6) is not cleared if a Serial Poll has occurred. A Factory Reset (*RST command) or power-on cycle will clear all bits in the condition register.
Return Format The command reads the condition register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register (see table above). For example, if bit 3 (decimal value = 8 and bit 5 (decimal value = 32) are set (and the corresponding bits are enabled), this command will return "+40".
Example The following command reads the condition register (bits 3 and 5 are set).

*TRG Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax *TRG
Description This command is used in conjunction with the TRIGger:SOURce command to trigger the instrument from the remote interface.
Remarks Use the TRIGger:SOURce command to select the BUS (software) trigger source. After setting the trigger source, you must place the multimeter in the "wait-for-trigger" state using the INITiate command. The *TRG command will not be accepted unless the multimeter is in the "wait-for-trigger" state.
Example The following command triggers the instrument.
See Also TRIGger:SOURce
*TST? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax *TST?
Description This command performs a complete self-test of the instrument and returns a pass/fail indication. The self-test runs a series of tests and will take several seconds to complete. If all tests pass, you can have a high confidence that the instrument is operational.
Remarks The 34410A/11A/L4411A self-test takes over five seconds to complete. When sending the *TST? command from the Agilent Connection Expert 'Interactive IO' window or from the Web-based 'SCPI Command Interface' window, it may be necessary to increase the timeout period to allow the command to complete without error. If one or more tests fail, "+1" is returned and an error is stored in the error queue. For a complete listing of the error messages related to selftest failures, see SCPI Error Messages.
Return Format The command returns "+0" (all tests passed) or "+1" (one or more tests failed).
Example The following command performs a self-test and returns a pass/fail indication.

MEASure Subsystem Introduction The MEASure? command provides the easiest way to program the instrument for measurements. However, this command does not offer much flexibility. When you execute this command, the instrument uses default values for the requested measurement configuration and immediately performs the measurement. You cannot change any measurement attributes (other than function, range, and resolution) before the measurement is taken.
Command Summary MEASure:CAPacitance? MEASure:CONTinuity? MEASure:CURRent:AC? MEASure:CURRent[:DC]? MEASure:DIODe? MEASure:FREQuency? MEASure:FRESistance? MEASure:PERiod? MEASure:RESistance? MEASure:TEMPerature? MEASure[:VOLTage]:AC? MEASure[:VOLTage][:DC]?
Default Settings for the MEASure? Command With the MEASure? command, you can select the function, range, and resolution all in one command. All other measurement parameters are set to their default values as shown below.
Using the MEASure? Command The following command shows how to use the MEASure? command to make a measurement. This example configures the instrument for dc voltage measurements, internally triggers the instrument to take a reading, and then transfers the reading to the instrument output buffer. The default range (autorange) and resolution (1 PLC) are used for the measurement. MEAS:VOLT:DC? Typical Response: +4.
MEASure:CAPacitance? Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax MEASure:CAPacitance? [{|AUTO|MIN|MAX|DEF} [, {|MIN|MAX|DEF}]]
Description First, this command resets all capacitance measurement parameters and trigger parameters to their default values. Then, it configures the meter for capacitance measurements and immediately triggers a measurement. The results are sent directly to the instrument output buffer.
Parameters Name Type Range of Values Default Value Desired range in F (farads): Numeric Numeric 1 nF (MIN) 10 nF 100 nF 1 µF 10 µF (MAX) AUTO (autorange) Desired resolution in F (farads). AUTO Fixed at 4½ digits.
Remarks The parameter is optional, and is in fact ignored. The resolution is actually fixed at 4½ digits. You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input.
Return Format The command returns a single reading.
Examples The following command configures the instrument for capacitance measurements, triggers the meter to take a reading, and then transfers the reading to the instrument output buffer. The default range (AUTO) and resolution (4½ digits) are used for the measurement. MEAS:CAP? Typical Response: +0.

Description First, this command resets all resistance measurement parameters and trigger parameters to their default values. Then, it configures the meter for 2-wire resistance measurements and immediately triggers a measurement. The results are sent directly to the instrument output buffer.
Parameters Name Type Range of Values Default Value Desired range in ohms: Numeric Numeric 100 Ω (MIN) 1 kΩ 10 kΩ 100 kΩ 1 MΩ 10 MΩ 100 MΩ 1 GΩ (MAX) AUTO (autorange) Desired resolution in ohms (see Resolution Table or Range, Resolution, and NPLC for more information). AUTO (autorange) 0.
Remarks You can allow the instrument to automatically select the measurement range using autoranging or you can select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which range to use for each measurement based on the input signal. For faster measurements, use manual ranging on each measurement (some additional time is required for autoranging since the instrument has to make a range selection).
Return Format The command returns a single reading.
Examples The following command configures the instrument for 2-wire resistance measurements, triggers the meter to take a reading, and then transfers the reading to the instrument output buffer. The default range (autorange) and resolution (1 PLC) are used for the measurement. MEAS:RES? Typical Response: +1.32130000E+04 The following command configures the instrument for 2-wire resistance measurements, triggers the meter to take a reading, and then transfers the reading to the instrument output buffer.

Syntax MEASure:TEMPerature? [{|DEF}[,{|DEF} [,1 [, {|MIN|MAX|DEF}]]]]
Description First, this command resets all temperature measurement parameters and trigger parameters to their default values. Then, it configures the meter for temperature measurements and immediately triggers a measurement. The results are sent directly to the instrument output buffer.
Parameters Name Type Discrete Range of Values Default Value {FRTD|RTD|FTHermistor|THERmistor} Required paramete DEF sets FRTD For THER: {2252|5000|10000} Required paramete DEF sets 5000 (2wire) {2252|5000|10000} Required paramete DEF sets 5000 (4wire) {85} Required paramete DEF sets 85 (2wire) {85} Required paramete DEF sets 85 (4wire) For FTH: Discrete For RTD: For FRTD: Numeric Desired resolution in the currently selected units (°C, °F, or K).
Remarks For temperature measurements, the instrument internally selects the range−you cannot select the range to be used. The range ("1" is the only allowed value) is used only in conjunction with resolution to determine NPLC. The range ("1") and parameters are optional. However, if you specify , you must also specify "1" as the implied range parameter (see syntax above). For example: MEAS:TEMP? THER,5000,1,0.1 specifies range = 1 and resolution = 0.
Return Format The command returns a single reading.
Examples The following command configures the instrument for 5 kΩ thermistor measurements, triggers the meter to take a reading, and then transfers the reading to the instrument output buffer. This 2-wire measurement is made with 0.1 °C resolution (assumes default temperature units). MEAS:TEMP? THER,5000,1,0.1 Typical Response: +2.47150000E+01 The following command configures the meter for a 2-wire RTD measurement, triggers the meter, and then transfers the reading to the instrument output buffer.

SAMPle Subsystem Introduction The SAMPle commands are used with the TRIGger commands to set up the triggering parameters. Use the SAMPle commands to set a sample count, sample source, and delay time for triggered sampling.
It is recommended that all triggered measurements be made using an appropriate fixed manual range. That is, turn autorange off (SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Command Summary SAMPle:COUNt SAMPle:COUNt? SAMPle:COUNt:PRETrigger SAMPle:COUNt:PRETrigger? SAMPle:SOURce SAMPle:SOURce? SAMPle:TIMer SAMPle:TIMer?
SAMPle:COUNt Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax SAMPle:COUNt {|MIN|MAX|DEF} SAMPle:COUNt? [{MIN|MAX}]
Description This command selects the number of readings (samples) the meter will take per trigger. It is recommended that all triggered measurements be made using an appropriate fixed manual range. That is, turn autorange off (SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Parameters Name Type Range of Values 1 to 50,000 samples (34410A) 1 to 1,000,000 samples (34411A/L4411A) Numeric MIN = 1 sample MAX = 50,000 samples (34410A) MAX = 1,000,000 samples (34411A/L4411A) Default Value 1 sample per trigger
Remarks The front-panel sample annunciator ( "*" ) turns on during each measurement at slower rates. However, the annunciator toggles at a fixed rate for fast measurements. The 34411A provides the pre-trigger feature for all measurement functions except CONTinuity and DIODe test. After setting the sample count, you must place the meter in the "wait-fortrigger" state using the INITiate or READ? command. An external trigger will be buffered until the meter is in the "wait-for-trigger" state.
Return Format The query command returns the sample count in the form "+1".
Examples The following command sets the meter's sample count to 10. When a trigger is received from the selected trigger source, the meter will make 10 measurements. SAMP:COUN 10 The following query returns the current sample count.

SAMPle:COUNt:PRETrigger (34411A/L4411A) Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax SAMPle:COUNt:PRETrigger {|MIN|MAX|DEF} SAMPle:COUNt:PRETrigger? [{MIN|MAX}]
Description The Agilent 34411A/L4411A provides a pretrigger feature that allows collection of the data being digitized before the trigger. This command reserves memory for pretrigger samples up to the specified number of readings (samples) to be taken before the trigger. It is recommended that all triggered measurements be made using an appropriate fixed manual range.
Parameters Name Type Range of Values 0 to 999,999 samples MIN = 0 sample Numeric MAX = 999,999 samples (MAX = 10,000 samples if CALC:STAT ON) Default Value This is a required parameter.
Remarks This command is supported by the 34411A and L4411A, but not the 34410A. The 34411A/L4411A provides the pre-trigger feature for all measurement functions except CONTinuity and DIODe test. Use the SAMPle:COUNt command to set the sample count (the total number of samples to take), and then use the SAMPle:COUNt:PRETrigger command to set the pretrigger sample count (the number of pretrigger samples to take).
trigger sample): Pretrigger Sample Count ≤ Sample Count - 1 If any of the calculation functions are on (CALC:STAT ON), the pretrigger count is further limited to 10,000 samples. The CONFigure and MEASure? commands automatically set the pretrigger sample count to "0". The instrument sets the pretrigger sample count to "0" after a Factory Reset ( *RST command) or a Preset (SYSTem:PRESet command). It is recommended that all triggered measurements be made using an appropriate fixed manual range.
Return Format The query command returns the pretrigger sample count in the form "+1".
Examples The following commands set the sample count to 10,000 and the pretrigger sample count to 5000 (so that 5000 samples will be taken before the trigger, and 5000 after). SAMP:COUN 10000 SAMP:COUN:PRET 5000 The following query returns the current sample count.

SAMPle:SOURce Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax SAMPle:SOURce {IMMediate|TIMer} SAMPle:SOURce?
Description This command works in conjunction with the TRIGger:DELay command and the SAMPle:TIMer command to determine sample timing when the sample count is greater than one. In all cases, the first sample is taken one trigger delay time after the trigger (the delay being set with the TRIGger:DELay command).
(SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Remarks This command has no effect if the sample count is 1 (see SAMPle:COUNt). After setting the sample count, sample source, and the sample interval or trigger delay time, you must place the instrument in the "wait-for-trigger" state using the INITiate or READ? command. A trigger will not be accepted from the selected trigger source (see TRIGger:SOURce command) until the instrument is in the "wait-for-trigger" state.
Return Format The query command returns "IMM" or "TIM".
Examples The following example sets the meter's sample source to "TIM". The INIT command sets the meter to the "wait-for-trigger" state. When a trigger is received from the selected trigger source, the instrument starts taking periodic samples after the current trigger delay. SAMP:SOUR TIM SAMP:TIM 0.1 INIT The following query returns the current sample source.
See Also TRIGger:COUNt TRIGger:DELay TRIGger:SOURce SAMPle:COUNt SAMPle:TIMer
SAMPle:TIMer Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax SAMPle:TIMer {|MIN|MAX} SAMPle:TIMer? [{MIN|MAX}]
Description This command sets a sample interval for timed sampling when the sample count is greater than one. Use the SAMPle:SOURce command to set the TIMer option for timed sampling. The first sample is taken one trigger delay time after the trigger (the delay being set with the TRIGger:DELay command).
Parameters Name Type Range of Values MIN to ~3600 seconds (~20 µs steps).* Numeric MIN = measurement dependent, MAX = ~3600 s. Default Value This is a required parameter * Step size for dc measurements is approximately 20 µs. Step size depends on ac bandwidth for ac measurements.
Remarks The value of MIN is measurement dependent. It depends on the integration time (resolution), whether autozero is on, whether autorange is on, and the measurement range. Basically, MIN is automatically determined so that the sample interval is always greater than the sampling time (see above illustration). However, the MIN value is not enforced, and you can specify an less than MIN (even zero). Execute SAMPle:TIMer? MIN to determine the current value of MIN.
Return Format The query command returns the sample interval in seconds. If you include MIN or MAX in the query, the returned value is the minimum or maximum recommended interval (for this command only) for the current measurement. The value returned by SAMPle:TIMer? MIN is affected by operations such as autorange, offset compensation (for resistance or temperature), and 100 PLC integration times, which require additional time.
Examples The following example sets the meter's sample interval to 0.1 seconds. The INIT command sets the meter to the "wait-for-trigger" state. When a trigger is received from the selected trigger source, the meter waits the current trigger delay, and then takes readings every 0.10 seconds until the current sample count is satisfied. SAMP:SOUR TIM SAMP:TIM 0.1 INIT The following query returns the current sample count. SAMP:TIM? Typical Response: 0.

Description This command disables or enables autoranging for capacitance measurements. Autoranging is convenient because the instrument automatically selects the range for each measurement based on the input signal detected.
Parameters Name Type Boolean Range of Values Default Value {OFF|0|ON|1|ONCE} This is a required parameter
Remarks Autorange thresholds: Down range at: <10% of range Up range at: >120% of range With autoranging enabled, the instrument selects the appropriate range based on the input signal detected. The ONCE parameter performs an immediate autorange, and then sets autoranging to OFF. (Thus, the query returns "0".) Selecting a discrete range (see [SENSe:]CAPacitance:RANGe[:UPPer] command) will disable autoranging.
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command disables autoranging. CAP:RANG:AUTO OFF The following query returns the autoranging settings.

[SENSe:]CURRent[:DC]:APERture Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax [SENSe:]CURRent[:DC]:APERture {|MIN|MAX|DEF} [SENSe:]CURRent[:DC]:APERture? [{MIN|MAX}]
Description This command selects the integration time in seconds (called aperture time) for dc current measurements. You should use this command only when you want precise control of the integration time of the multimeter. Otherwise, specifying integration time using NPLC (see [SENSe:]CURRent[:DC]:NPLC command) offers better power-line noise rejection characteristics (for values of NPLC greater than 1).
Parameters Name Type Range of Values* Default Value Desired aperture time in seconds: 34410A: ~100 µs to ~1 s (with ~20 µs resolution). Numeric MIN = ~100 µs, MAX = ~1 s 34411A: ~20 µs to ~1 s (with ~20 µs resolution).
Remarks Due to internal quantization, the actual aperture that you set may be slightly different than your specified value. The increment is approximately 20 µs. Use the query command to determine the exact aperture that is set. For example, if you send "CURR:DC:APER 500 ms", and then send the query "CURR:DC:APER?" the actual aperture is returned (for example: "+5.00000753E-01"). Setting an aperture with this command changes any integration time selected with the [SENSe:]CURRent[:DC]:NPLC command.
Return Format The query command returns the aperture time in the form "+1.00000000E01".
Examples The following command sets the aperture time to 300 ms. CURR:DC:APER 300E-03 The following query returns the aperture time selected. CURR:DC:APER? Typical Response: +3.

[SENSe:]CURRent[:DC]:ZERO:AUTO Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax [SENSe:]CURRent[:DC]:ZERO:AUTO [SENSe:]CURRent[:DC]:ZERO:AUTO?
Description This command disables or enables the autozero mode for dc current measurements. When autozero is ON (default), the instrument internally disconnects the input signal following each measurement, and takes a zero reading. It then subtracts the zero reading from the preceding reading. This prevents offset voltages present on the instrument's input circuitry from affecting measurement accuracy.
Parameters Name Type Range of Values Default Value Discrete {OFF|0|ON|1|ONCE} Autozero ON
Remarks Autozero ONCE issues an immediate zero measurement, and then sets autozero to OFF. The autozero mode is set indirectly when you set the resolution and integration time using the CONfigure or MEASure commands. Autozero is automatically turned off when you select an integration time less than 1 PLC with these commands. The autozero mode is reset to the default (ON) at power up, or after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns "0" (OFF or ONCE) or "1" (ON).
Examples The following command disables autozero. With autozero disabled, a new zero measurement is not issued until the next configuration change (function, range, NPLC, or aperture). CURR:ZERO:AUTO OFF The following query returns the autozero settings.

Syntax [SENSe:]FREQuency:VOLTage:RANGe:AUTO [SENSe:]FREQuency:VOLTage:RANGe:AUTO?
Description This command disables or enables voltage autoranging for frequency measurements. Autoranging is convenient because the instrument automatically selects the range for each measurement based on the input ac voltage detected. The maximum range parameter is 1000 V. However, the SAFETY LIMIT on the front and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform dependent. A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is safe.
Parameters Name Type Range of Values Default Value Boolean {OFF|0|ON|1|ONCE} Autorange ON
Remarks Autorange thresholds: Down range at: <10% of range (ac voltage) Up range at: >120% of range (ac voltage) With autoranging enabled, the instrument selects the appropriate voltage range based on the input signal detected. The ONCE parameter performs an immediate autorange, and then sets autoranging to OFF. (Thus, the query returns "0".) Selecting a discrete range (see [SENSe:]FREQuency:VOLTage:RANGe command) will disable autoranging.
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command disables autoranging. FREQ:VOLT:RANG:AUTO OFF The following query returns the autoranging setting.

Syntax [SENSe:]PERiod:RANGe:LOWer {|MIN|MAX|DEF} [SENSe:]PERiod:RANGe:LOWer? [{MIN|MAX}]
Description This command sets the ac bandwidth used to detect the signal during period and frequency measurements. The instrument uses three different ac filters. The instrument selects the slow (3 Hz), medium (20 Hz), or fast (200 Hz) filter based on the cutoff frequency that you specify with this command. Set the lowest expected frequency that you expect to encounter. The default is 20 Hz (medium).
Parameters Name Type Discrete Range of Values Default Value {3|20|200} This is a required parameter.
Remarks Applies to period and frequency measurements, and to voltage measurements made as the second display function during frequency or period measurements. The parameter takes on one of three discrete values: 3, 20, or 200. However, you can enter the lowest expected frequency that you intend to encounter, and the command will automatically enter the appropriate value for . For example, if you enter 15 Hz, the slow filter (3 Hz) is selected.
Return Format The query command returns "3.0000000" (slow), "2.0000000E+1" (medium), or "2.0000000E+2" (fast).

[SENSe:]PERiod:VOLTage:RANGe:AUTO Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax [SENSe:]PERiod:VOLTage:RANGe:AUTO [SENSe:]PERiod:VOLTage:RANGe:AUTO?
Description This command disables or enables voltage autoranging for period measurements. Autoranging is convenient because the instrument automatically selects the range for each measurement based on the input ac voltage detected. The maximum range parameter is 1000 V. However, the SAFETY LIMIT on the front and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform dependent. A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is safe.
Parameters Name Type Range of Values Default Value Boolean {OFF|0|ON|1|ONCE} Autorange ON
Remarks Autorange thresholds: Down range at: <10% of range (ac voltage) Up range at: >120% of range (ac voltage) With autoranging enabled, the instrument selects the appropriate voltage range based on the input signal detected. The ONCE parameter performs an immediate autorange, and then sets autoranging to OFF. (Thus, the query returns "0".) Selecting a discrete range (see [SENSe:]PERiod:VOLTage:RANGe command) will disable autoranging.
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command disables autoranging. PER:VOLT:RANG:AUTO OFF The following query returns the autoranging setting.

It then subtracts the zero reading from the preceding reading. This removes offset variations present on the instrument's input circuitry that might affect measurement accuracy.
Parameters Name Type Range of Values Default Value Discrete {OFF|0|ON|1|ONCE} Autozero ON
Remarks This command does not affect 4-wire resistance measurements. All 4-wire measurements are made with autozero ON, regardless of the state set or returned by this command or query. Autozero ONCE issues an immediate zero measurement, and then sets autozero to OFF. The autozero mode is set indirectly when you set the resolution and integration time using the CONfigure or MEASure commands. Autozero is automatically turned off when you select an integration time less than 1 PLC with these commands.
Return Format The query command returns "0" (OFF or ONCE) or "1" (ON).
Examples The following command disables autozero. With autozero disabled, a new zero measurement is not issued until the next configuration change (function, range, NPLC, or aperture). RES:ZERO:AUTO OFF The following query returns the autozero setting.

Syntax [SENSe:]TEMPerature:APERture {|MIN|MAX|DEF} [SENSe:]TEMPerature:APERture? [{MIN|MAX}]
Description This command selects the integration time in seconds (called aperture time) for temperature measurements. You should use this command only when you want precise control of the integration time of the multimeter. Otherwise, specifying integration time using NPLC (see [SENSe:]TEMPerature:NPLC command) offers better power-line noise rejection characteristics (for values of NPLC greater than 1).
Parameters Name Type Range of Values* Default Value Desired aperture time in seconds: 34410A: ~100 µs to ~1 s (with ~20 µs resolution). Numeric MIN = ~100 µs, MAX = ~1 s 34411A/L4411A: ~20 µs to ~1 s (with ~20 µs resolution).
Remarks Due to internal quantization, the actual aperture that you set may be slightly different than your specified value. The increment is approximately 20 µs. Use the query command to determine the exact aperture that is set. For example, if you send "TEMP:APER 500 ms", and then send the query "TEMP:APER?" the actual aperture is returned (for example: "+5.00000753E-01"). Setting an aperture with this command changes any integration time selected with the [SENSe:]TEMPerature:NPLC command.
Return Format The query command returns the aperture time in the form "+1.00000000E01".
Examples The following command sets the aperture time to 300 ms. TEMP:APER 300E-03 The following query returns the aperture time selected. TEMP:APER? Typical Response: +3.

Syntax [SENSe:]VOLTage:AC:RANGe:AUTO [SENSe:]VOLTage:AC:RANGe:AUTO?
Description This command disables or enables autoranging for ac voltage measurements. Autoranging is convenient because the instrument automatically selects the range for each measurement based on the input signal detected. The maximum range parameter is 1000 V. However, the SAFETY LIMIT on the front and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform dependent. A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is safe.
Parameters Name Type Range of Values Default Value Boolean {OFF|0|ON|1|ONCE} Autorange ON
Remarks Autorange thresholds: Down range at: <10% of range Up range at: >120% of range With autoranging enabled, the instrument selects the appropriate range based on the input signal detected. The ONCE parameter performs an immediate autorange, and then sets autoranging to OFF. (Thus, the query returns "0".) Selecting a discrete range (see [SENSe:]VOLTage:AC:RANGe command) will disable autoranging.
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command disables autoranging. VOLT:AC:RANG:AUTO OFF The following query returns the autoranging setting.

Description This command selects the measurement range for ac voltage measurements. The maximum range parameter is 1000 V, which is set by MAX. However, the SAFETY LIMIT on the front and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform dependent. A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is safe. Connections to AC MAINS are further limited to CAT II (300V).
Parameters Name Type Range of Values Desired range in volts: Discrete 100 mV (MIN) 1V 10 V 100 V 1000 V (MAX) Default Value This is a required parameter.
Remarks Selecting a discrete range will disable autoranging. If the input signal is greater than can be measured on the selected range (manual ranging), the instrument gives an overload indication: "OVLD" from the front panel or "+9.9E+37" from the remote interface. The instrument is set to 10 V, with autoranging enabled, after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns the range in the form "+1.00000000E+01".
Examples The following command selects the 10 volt range. VOLT:AC:RANG 10 The following query returns the range selected. VOLT:AC:RANG? Typical Response: +1.

Description This command selects the integration time in seconds (called aperture time) for dc voltage measurements. You should use this command only when you want precise control of the integration time of the multimeter. Otherwise, specifying integration time using NPLC (see [SENSe:]VOLTage[:DC]:NPLC command) offers better power-line noise rejection characteristics (for values of NPLC greater than 1).
Parameters Name Type Range of Values* Default Value Desired aperture time in seconds: 34410A: ~100 µs to ~1 s (with ~20 µs resolution). Numeric MIN = ~100 µs, MAX = ~1 s 34411A/L4411A: ~20 µs to ~1 s (with ~20 µs resolution).
Remarks Due to internal quantization, the actual aperture that you set may be slightly different than your specified value. The increment is approximately 20 µs. Use the query command to determine the exact aperture that is set. For example, if you send "VOLT:DC:APER 500 ms", and then send the query "VOLT:DC:APER?" the actual aperture is returned (for example: "+5.00000753E-01"). Setting an aperture with this command changes any integration time selected with the [SENSe:]VOLTage[:DC]:NPLC command.
Return Format The query command returns the aperture time in the form "+1.00000000E01".
Examples The following command sets the aperture time to 300 ms. VOLT:DC:APER 300E-03 The following query returns the aperture time selected. VOLT:DC:APER? Typical Response: +3.

Parameters Name Type Range of Values* 34410A: {0.006|0.02|0.06|0.2|1|2|10|100} MIN = 0.006 PLC, MAX = 100 PLC Discrete Defa Value 34411A/L4411A: {0.001|0.002|0.006|0.02|0.06|0.2|1|2|10|100} MIN = 0.001 PLC, MAX = 100 PLC See Range, Resolution, and NPLC for more information.
Remarks Selecting an integration time with this command changes any aperture set with the [SENSe:]VOLTage[:DC]:APERture command. Only those integration times set to an integral number of power line cycles (1, 2, 10, or 100 PLCs) provide normal mode (line frequency noise) rejection. Setting the integration time also sets the resolution for the measurement. The following table shows the relationship between integration time and resolution. Integration Time (power line cycles) Resolution 0.
(*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns the integration time in the form "+1.00000000E+00".
Examples The following command set the integration time to 0.2 PLCs. VOLT:DC:NPLC 0.2 The following query returns the integration time setting. VOLT:DC:NPLC? Typical Response: +2.

Syntax [SENSe:]VOLTage[:DC]:RANGe:AUTO [SENSe:]VOLTage[:DC]:RANGe:AUTO?
Description This command disables or enables autoranging for dc voltage measurements. Autoranging is convenient because the instrument automatically selects the range for each measurement based on the input signal detected.
Parameters Name Type Range of Values Default Value Boolean {OFF|0|ON|1|ONCE} Autorange ON
Remarks Autorange thresholds: Down range at: <10% of range Up range at: >120% of range With autoranging enabled, the instrument selects the appropriate range based on the input signal detected. The ONCE parameter performs an immediate autorange, and then sets autoranging to OFF. (Thus, the query returns "0".) Selecting a discrete range (see [SENSe:]VOLTage[:DC]:RANGe command) will disable autoranging.
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command disables autoranging. VOLT:DC:RANG:AUTO OFF The following query returns the autoranging setting.

[SENSe:]VOLTage[:DC]:RESolution Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax [SENSe:]VOLTage[:DC]:RESolution {|MIN|MAX|DEF} [SENSe:]VOLTage[:DC]:RESolution? [{MIN|MAX}]
Description This command selects the measurement resolution for dc voltage measurements. Specify the resolution in the same units as the selected measurement function, not in number of digits.
Parameters Name Type Range of Values Default Value Numeric Desired resolution in volts (see Resolution Table). 0.
Remarks Setting the resolution with this command changes any aperture set with the [SENSe:]VOLTage[:DC]:APERture command. For the parameter, you can substitute MIN or MAX for a numeric value. MIN selects the smallest value accepted, which gives the highest resolution; MAX selects the largest value accepted, which gives the least resolution.
Return Format The query command returns the resolution in the form "+1.00000000E-03".
Examples The following command sets the measurement resolution to 1 mV. VOLT:DC:RES 1E-03 The following query returns the resolution selected. VOLT:DC:RES? Typical Response: +1.

[SENSe:]VOLTage[:DC]:ZERO:AUTO Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax [SENSe:]VOLTage[:DC]:ZERO:AUTO [SENSe:]VOLTage[:DC]:ZERO:AUTO?
Description This command disables or enables the autozero mode for dc voltage measurements. When autozero is ON (default), the instrument internally disconnects the input signal following each measurement, and takes a zero reading. It then subtracts the zero reading from the preceding reading. This prevents offset voltages present on the instrument's input circuitry from affecting measurement accuracy.
Parameters Name Type Discrete Range of Values Default Value {OFF|0|ON|1|ONCE} This is a required parameter
Remarks Autozero ONCE issues an immediate zero measurement, and then sets autozero to OFF. The autozero mode is set indirectly when you set the resolution and integration time using the CONfigure or MEASure commands. The autozero mode is reset to the default (ON) at power up, or after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns "0" (OFF or ONCE) or "1" (ON).
Examples The following command disables autozero. With autozero disabled, a new zero measurement is not issued until the next configuration change (function, range, NPLC, or aperture). VOLT:ZERO:AUTO OFF The following query returns the autozero setting.

Syntax SYSTem:COMMunicate:LAN:DHCP SYSTem:COMMunicate:LAN:DHCP?
Description This command disables or enables use of the Dynamic Host Configuration Protocol (DHCP) for the 34410A/11A/L4411A. When DHCP is enabled (factory setting), the 34410A/11A/L4411A will try to obtain an IP address from a DHCP server. If a DHCP server is found, it will assign a dynamic IP address, Subnet Mask, and Default Gateway to the instrument. When DHCP is disabled or unavailable, the 34410A/11A/L4411A will use the static IP address, Subnet Mask, and Default Gateway during power-on.
Parameters Name Type Boolean Range of Values Default Value {OFF|0|ON|1} This is a required parameter
Remarks Most corporate LANs have a DHCP server. If a DHCP LAN address is not assigned by a DHCP server, then a static IP will be assumed after approximately 2 minutes. See the SYSTem:COMMunicate:LAN:BSTatus? command for more information on the instrument's boot status. The DHCP setting is stored in non-volatile memory, and does not change when power has been off, after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command disables DHCP. SYST:COMM:LAN:DHCP OFF The following query returns the current DHCP setting.

" SYSTem:COMMunicate:LAN:DNS? [{CURRent|STATic}]Description This command assigns the static DNS address (the IP address of the Domain Name System server). Contact your network administrator to determine if DNS is being used and for the correct address. If DHCP is available and enabled, DHCP will auto-assign the DNS address. This auto-assigned DNS address takes precedence over the static DNS address assigned with this command. If you change the DNS address, you must cycle power on the instrument to activate the new setting.
Parameters Name
Type Range of Values Default Value Quoted String Specified in four-byte dot notation ("nnn.nnn.nnn.nnn"), where "nnn" in each case is a byte value in the range 0 through 255. "0.0.0.Remarks The assigned DNS address is used for the DNS server if DHCP is disabled or unavailable. Otherwise, the DNS server address is auto-assigned by DHCP. Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value) must be expressed with care, as most web software on the PC will interpret byte values with leading zeros as octal numbers. For example, "255.255.020.011" is actually equivalent to decimal "255.255.16.9" not "255.255.20.11" because ".
Return Format The query command returns the current DNS address in the form "nnn.nnn.nnn.nnn". Note that the query command has two optional parameters. Specify "CURRent" (default) to read the DNS address currently being used by the instrument. Specify "STATic" to read the static DNS address currently stored in non-volatile memory within the instrument. This is the address that is used if DHCP is disabled or currently unavailable.
Examples The following command sets the static DNS address. SYST:COMM:LAN:DNS "198.105.232.4" The following query returns the DNS address currently being used by the instrument (the quotes are also returned). SYST:COMM:LAN:DNS? CURR Typical Response: "198.105.232.

Syntax SYSTem:LFRequency?
Description This command returns the current power-line reference frequency used by the 34410A/11A/L4411A analog-to-digital converter. You can set this reference frequency with the CALibration:LFRequency command. Normally, when you apply power to the instrument, the instrument automatically detects the power-line frequency (50 Hz, 60 Hz, or 400 Hz) and uses this value to determine the integration time used.
Remarks If the detected power line frequency is 400 Hz, the 50 Hz reference value is actually used (a subharmonic of 400 Hz). The instrument multiplies the period of the reference frequency by the specified number of power line cycles ([SENSe:]:NPLC commands) to determine the actual integration time. The reference frequency setting is stored in volatile memory and will be lost when power is turned off.
Return Format The command returns "50" (for 50 Hz or 400 Hz) or "60" indicating the present reference frequency setting.
Example The following command sets the reference frequency setting to 50 Hz. SYST:LFR 50 The following command returns the reference frequency setting.

SYSTem:LOCK:REQuest? Syntax | Description | Parameters | Remarks | Return Format | Example
Syntax SYSTem:LOCK:REQuest?
Description This command requests a lock of the current I/O interface. This provides a mechanism by which you can lock the instrument's configuration or cooperatively share the instrument with other computers.
Remarks Lock requests can be nested and each request will increase the lock count by 1. For every request, you will need a release from the same I/O interface (see SYSTem:LOCK:RELease command). Instrument locks are handled at the I/O interface level (GPIB, USB, LAN, etc.) and you are responsible for all coordination between threads and/or programs on that interface. When a request is granted, only I/O sessions from the present interface will be allowed to change the state of the instrument.
Return Format The command returns "+1" if the lock request is granted or "+0" if denied.
Example The following command requests a lock of the current I/O interface.

Syntax TRIGger:COUNt {|MIN|MAX|DEF|INFinity} TRIGger:COUNt? [{MIN|MAX}]
Description This command selects the number of triggers that will be accepted by the meter before returning to the "idle" trigger state. It is recommended that all triggered measurements be made using an appropriate fixed manual range. That is, turn autorange off (SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Parameters Name Type Range of Values Default Value 34410A: 1 to 50,000 triggers, or continuous (INFinity). MIN = 1 trigger MAX = 50,000 triggers Numeric 34411A/L4411A: 1 to 1,000,000 triggers, or continuous (INFinity).
Remarks The selected trigger count applies to the trigger source set by the TRIGger:SOURce command. a. For the BUS source, the trigger count sets the number of *TRG commands that will be accepted before returning to the "idle" trigger state. b. For the IMMediate source, the trigger count just controls the number of readings to be taken. c. For the EXTernal source, the trigger count sets the number of external pulses that will be accepted before returning to the "idle" trigger state.
Return Format The query command returns the trigger count in the form "+1.00000000E+00". For a continuous trigger (INFinity), the query command returns "+9.90000000E+37".

TRIGger:DELay Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax TRIGger:DELay {|MIN|MAX|DEF} TRIGger:DELay? [{MIN|MAX}]
Description This command sets the delay between the trigger signal and the first measurement. This may be useful in applications where you want to allow the input to settle before taking a reading or for pacing a burst of readings. The programmed trigger delay overrides the default trigger delay that the instrument automatically adds. It is recommended that all triggered measurements be made using an appropriate fixed manual range.
Parameters Name Type Range of Values Default Value This is a required parameter. Numeric 0 to ~3600 seconds (~20 µs increment for dc measurements).
Remarks The CONTinuity and DIODe test functions ignore the trigger delay setting. Due to internal quantization, the actual delay that you set may be slightly different than your specified value. The increment is approximately 20 µs. Use the query command to determine the exact delay that is set. For example, if you send "TRIG:DEL 500 ms", and then send the query "TRIG:DEL?" the actual delay is returned (for example: "+5.00000753E01"). For ac measurements, the delay is based on the detector bandwidth.
Return Format The query command returns the delay in seconds.
Examples The following command sets a 2-second trigger delay. TRIG:DEL 2 The following query returns the trigger delay selected. TRIG:DEL? Typical Response: +2.

TRIGger:DELay:AUTO Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax TRIGger:DELay:AUTO TRIGger:DELay:AUTO?
Description This command disables or enables an automatic trigger delay. If enabled, the instrument determines the delay based on function, range, and integration time or bandwidth. It is recommended that all triggered measurements be made using an appropriate fixed manual range. That is, turn autorange off (SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Parameters Name Type Boolean Range of Values Default Value {OFF|0|ON|1} This is a required parameter.
Remarks Selecting a specific trigger delay using the TRIGger:DELay command disables the automatic trigger delay. The CONFigure and MEASure? commands set the trigger delay to Automatic. The instrument enables an automatic trigger delay after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command). It is recommended that all triggered measurements be made using an appropriate fixed manual range.
Return Format The query command returns "0" (OFF) or "1" (ON).
Examples The following command enables an automatic trigger delay. TRIG:DEL:AUTO ON The following query returns the automatic trigger delay setting.

TRIGger:LEVel (34411A/L4411A) Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax TRIGger:LEVel {|MIN|MAX|DEF} TRIGger:LEVel? [{MIN|MAX}]
Description The 34411A and L4411A (but not the 34410A) allow you to trigger on a defined level of the input signal. This command sets the level on which a trigger occurs when the trigger source is set to INTernal (see TRIGger:SOURce). It is recommended that all triggered measurements be made using an appropriate fixed manual range. That is, turn autorange off (SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Parameters If autoranging is off, the parameter can take any value between 120% and +120% of the present range for the currently selected function. The is entered in the fundamental units for the function (that is volts, ohms, or amperes). MIN = -120% and MAX = +120%. Default = 0. This is a required parameter. If autoranging is on, can take any value between -120% and +120% of the highest range for the currently selected function.
Remarks This command is supported by the 34411A and L4411A. This command is supported only for ac and dc voltage, ac and dc current, and 2-wire and 4-wire resistance measurements. To use the trigger level you must select INTernal as the trigger source with the TRIGger:SOURce command. If a manual range is selected, the accuracy of the trigger level is ±1 percent of the selected range.
Return Format The query command returns the current trigger level.
Examples The following commands set up the 34411A for level triggering. The CONFigure command configures the instrument for dc voltage measurements. The 1 V range is selected with 0.1 mV resolution. The TRIGger:SOURce command selects INTernal as the source. The TRIGger:LEVel command sets the trigger level at 0.75 volts. The INITiate command puts the instrument into the "wait for trigger" mode. CONF:VOLT:DC 1,0.0001 TRIG:SOUR INT TRIG:LEV 0.75 INIT The following query returns the current trigger level.
See Also TRIGger:DELay TRIGger:SOURce
TRIGger:SLOPe Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax TRIGger:SLOPe TRIGger:SLOPe?
Description This command selects whether the instrument uses the rising edge or the falling edge of the trigger signal on the rear-panel Ext Trig BNC connector. The default is NEG (falling edge). For the 34411A and L4411A, this command also affects the slope of detection for an internal trigger on a defined level (see the TRIGger:LEVel command). It is recommended that all triggered measurements be made using an appropriate fixed manual range.
Parameters Name Type Range of Values Default Value Discrete {POSitive|NEGative} NEG
Remarks The actual trigger event occurs on either the rising edge (if POS is selected) or the falling edge (if NEG is selected) of the trigger signal. See Ext Trig Input for further information. The instrument selects a negative slope after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command). It is recommended that all triggered measurements be made using an appropriate fixed manual range.
Return Format The query command returns either "POS" or "NEG".
Examples The following command sets the trigger slope to negative (falling edge). TRIG:SLOP NEG The following query returns currently selected trigger slope.
See Also Ext Trig Input TRIGger:LEVel TRIGger:SOURce
TRIGger:SOURce Syntax | Description | Parameters | Remarks | Return Format | Examples
Syntax TRIGger:SOURce TRIGger:SOURce?
Description This command selects the trigger source for measurements. The instrument will accept a software (bus) command, an immediate (continuous) trigger, or an external TTL trigger pulse. The 34411A and L4411A will also accept a trigger level. It is recommended that all triggered measurements be made using an appropriate fixed manual range. That is, turn autorange off (SENSe::RANGe:AUTO OFF), or set a fixed range using the SENSe::RANGe, CONFigure, or MEASure command.
Parameters Name Type Discrete Range of Values 34410A: {IMMediate|EXTernal|BUS} 34411A/L4411A: {IMMediate|EXTernal|BUS|INTernal} Default Value This is a required parameter.
Remarks After selecting the trigger source, you must place the instrument in the "wait-for-trigger" state using the INITiate or READ? command. A trigger will not be accepted from the selected trigger source until the instrument is in the "wait-for-trigger" state. For the IMMediate (continuous) source, the trigger signal is always present. When you place the instrument in the "wait-for-trigger" state, the trigger is issued immediately.
Return Format The query command returns the present trigger source: "IMM", "EXT", "BUS", or "INT" (34411A/L4411A).
Examples The following command selects the external trigger source. In this configuration, the instrument is triggered once each time a low-true TTL pulse is received on the rear-panel Ext Trig Input connector. TRIG:SOUR EXT INIT The following command selects the bus (software) trigger source. Note that the *TRG command will not be accepted unless the instrument is in the "wait-for-trigger" state. TRIG:SOUR BUS INIT *TRG The following query returns the trigger source currently selected.

SCPI Error Messages Execution Errors (-101...) | Instrument Errors (200...) | Self-Test Errors (600...) | Calibration Errors (700...) | Firmware Update Errors (700...) The Agilent 34410A/11A/L4411A returns error messages in accord with the SCPI standard. A record of up to 20 errors can be stored in the instrument's error queue. Each remote interface I/O session (GPIB, USB, VXI-11, Telnet/Sockets) has its own interface-specific error queue.
command and when power is cycled. All errors are cleared when you read the error queue. The error queue is not cleared by a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command). Front-Panel Operation: If the ERROR annunciator is on, there are errors in the error queue. The Remote annunciator is likely on as well. Press the [Shift] (Local) key to return the instrument to local operation (the Remote annunciator will go off).

Self-Test Errors The 34410A/11A/L4411A self-test (see the *TST? command) performs a series of tests on the instrument hardware. Any failure of these tests will generate a SCPI error number -330, with additional test failure information. Refer to the Agilent 34410A/11A/L4411A Service Guide for more information. The form of this error message is as follows: -330,"Self-test failed; " Where test# is the number of the test that failed (range 600 - 622) and testname describes the test.

Power-On and Reset State The following tables show the factory defaults for various instrument settings. The parameters marked with a bullet (•) are stored in non-volatile memory, and are not affected by power-on or a system reset. Other parameters are stored in volatile memory and are reset to the indicated values at power-on or after a *RST or SYSTem:PRESet command is issued. The power-on/reset state may be different than that in the tables if you have enabled the power-on state recall mode.

Automatic Trigger Delays If you do not specify a trigger delay in the TRIGger:DELay command, the instrument selects a delay for you. The delay is determined by the function, range, integration time, and ac filter setting as shown below. See the TRIGger:DELay and TRIGger:DELay:AUTO commands. For measurements from the remote interface, the automatic trigger delay values are as shown in the following tables.
