2 This chapter provides key descriptions and programming information for the front-panel key functions of your analyzer starting with the letters A through L. The front-panel functions are listed alphabetically and are described with their associated menu keys. The lower-level menu keys are arranged and described as they appear in your analyzer.
Instrument Functions: A − L The front- and rear-panel features, along with the numeric keypad and alpha-numeric softkey fundamentals are illustrated and described, in your Getting Started guide.
Instrument Functions: A - L AMPLITUDE / Y Scale AMPLITUDE / Y Scale Activates the Reference Level function and displays the Amplitude menu keys. These functions control how data on the vertical (Y) axis is displayed and corrected, and control instrument settings that affect the vertical axis. 2.0.1 Ref Level Enables you to adjust the absolute amplitude represented by the top graticule line on the display (the reference level). Ref in the upper left corner of the display, indicates the current value.
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.2 Attenuation Allows you to adjust the input attenuation. Press Atten Step to set the attenuation step so that attenuation will change in 2 dB or 10 dB increments. The analyzer input attenuator reduces the power level of the input signal delivered to the input mixer. If set manually, the attenuator is recoupled when Attenuation (Auto) is selected. To enter a value below 6 dB, you must use the front-panel numeric keypad.
Instrument Functions: A - L AMPLITUDE / Y Scale POW:ATT:AUTO? Instrument Functions: A - L Chapter 2 51
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.3 Scale/Div Sets the units per vertical graticule division on the display. This function is only available when Scale Type (Log) is selected and the vertical scale is power, or Demod View is on and the vertical scale is hertz. When Scale Type (Lin) is selected, Scale/Div is greyed out.
Instrument Functions: A - L AMPLITUDE / Y Scale Factory Preset: Log Instrument Functions: A - L Chapter 2 53
Instrument Functions: A - L AMPLITUDE / Y Scale Remote Command: :DISPlay:WINDow[1]:TRACe:Y:[SCALe]:SPACing LINear|LOGarithmic :DISPlay:WINDow[1]:TRACe:Y:[SCALe]:SPACing? Example: DISP:WIND:TRAC:Y:SPAC LOG DISP:WIND:TRAC:Y:SPAC? 2.0.5 Presel Center Adjusts the centering of the preselector filter to optimize the amplitude accuracy at the active marker frequency. If no marker is on when Presel Center is pressed, the analyzer turns on the currently selected marker and places it on the peak signal.
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.6 Presel Adjust Allows you to manually adjust the preselector filter frequency to optimize its response on the signal of interest. This function is only available when measuring signals ≥2.85 GHz in band 1 and higher bands. For analyzers that have both millimeter wave and microwave types of bands (E4448A and E4446A analyzers) the adjustment is band specific.
Instrument Functions: A - L AMPLITUDE / Y Scale [:SENSe]:POWer[:RF]:MMW:PADJust? Example: POW:MW:PADJ 100 POW:MW:PADJ? 2.0.7 Y Axis Units Displays the menu keys that enable you to change the vertical (Y) axis amplitude units. The analyzer retains the entered Y Axis Units separately for both Log and Lin amplitude scale types. For example, if Scale Type has been set to Log, and you set Y Axis Units to dBm, pressing Scale Type (Log) sets the Y Axis Units to dBm .
Instrument Functions: A - L AMPLITUDE / Y Scale This sets the top line to 100 mV and the bottom line to 0 V, so each vertical division represents 10 mV. Thus, if a point on trace 1 is on the fifth graticule line from the top, it represents 50 mV and will read out remotely as 50. Example: UNIT:POW dBmV UNIT:POW? 2.0.7.1 dBm Sets the amplitude units to dBm. Key Path: AMPLITUDE / Y Scale, More, Y Axis Units Remote Command: See “Y Axis Units” on page 56. Example: 2.0.7.
Instrument Functions: A - L AMPLITUDE / Y Scale Remote Command: See “Y Axis Units” on page 56. Example: 2.0.7.5 UNIT:POW V Watts Sets the amplitude units to watts. Key Path: AMPLITUDE / Y Scale, More, Y Axis Units Remote Command: See “Y Axis Units” on page 56. Example: 2.0.8 UNIT:POW W Ref Lvl Offset Allows you to add an offset value to the displayed reference level. The reference level is the absolute amplitude represented by the top graticule line on the display.
Instrument Functions: A - L AMPLITUDE / Y Scale Annotation: The offset is displayed to left of Trace window; third from the top, just below the scale type. State Saved: Saved in Instrument State Factory Preset: 0.0 dB Range: –327.6 dB to 327.6 dB Remote Command: :DISPlay:WINDow[1]:TRACe:Y:[SCALe]:RLEVel:OFFSet (in dB) :DISPlay:WINDow[1]:TRACe:Y:[SCALe]:RLEVel:OFFSet? Example: 2.0.9 DISP:WIND:TRAC:Y:RLEV:OFFS 12.7 Sets the Ref Level Offset to 12.7 dB. The only valid suffix is dB.
Instrument Functions: A - L AMPLITUDE / Y Scale select which set of correction factors you wish to modify. These frequency/amplitude corrections will be applied to the displayed data to correct for system losses/gains outside the analyzer. Four different sets of correction data can be stored. Key Path: AMPLITUDE / Y Scale, More Remote Command: Instrument Functions: A - L There is no equivalent remote command for this key.
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.10.1 Apply Corrections Pressing Apply Corrections (Yes) turns on the amplitude-correction factors. Corrections will only be applied for the sets of correction factors whose correction state is set to On. To turn a set of correction factors on, use the Correction On Off key in the Antenna, Cable, Other, or User menus.
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.10.2.1 Correction Turns the amplitude correction function on or off for the specific set of correction data. The corrections state must be set to On for the correction to be applied. Antenna, Cable, and Other correction factors are generally entered as positive values. This indicates a loss in the external device. User correction factors are NOTE typically entered as negative values which indicate a gain in the external device.
Instrument Functions: A - L AMPLITUDE / Y Scale data is merged, as many points as possible are merged into the existing data and then an error is reported.
Instrument Functions: A - L AMPLITUDE / Y Scale Remote Command Notes: [:SENSe]:CORRection:CSET:ALL[:STATe] must be set to on for this command to function.

Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.10.2.2.3 Amplitude Allows you to enter the amplitude value for the current amplitude-correction point. After entering an amplitude, the point number automatically increments and Frequency becomes active to allow entry of the frequency of the next point. Key Path: AMPLITUDE / Y Scale, More, Corrections, Antenna (Cable, Other, or User), Edit State Saved: Not part of instrument state, saved in a corrections file.
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.10.3 Freq Interp Allows you to determine how trace values are computed between points in a correction table. If the linear mode is selected, a straight line is used between points in the correction table (for a linear frequency scale and for a decibel amplitude scale).
Instrument Functions: A - L AMPLITUDE / Y Scale 2.0.11 Ext Amp Gain Compensates for external gain/loss. The function is similar to the Ref Lvl Offset function, however the value is considered, along with the maximum mixer level setting, to determine the attenuation required (10 dB of Attenuation is added for every 10 dB of External Amp Gain). The gain is subtracted from the amplitude readout so that the displayed signal level represents the signal level at the input of the external device.
Instrument Functions: A - L AMPLITUDE / Y Scale Sets the Attenuation to 10 dB. The only valid suffix is dB. If no suffix is sent, dB is assumed. If a value >5 is entered, 10 is used. If a value ≤5 is entered, 2 is used for PSA, or 5 is used for ESA. 2.0.13 Max Mixer Lvl Enables you to set the relationship between the highest signal that can be displayed (the reference level) and the input attenuation. The relationship applies whenever the Attenuation is set to Auto.

Instrument Functions: A - L Auto Couple 2.1 Auto Couple Coupled functions are functions that are linked/dependent on other functions. Pressing Auto Couple displays some of the most important coupled analyzer functions. An example of a coupled function is Res BW (resolution bandwidth). When Res BW is set to auto, the Res BW is automatically set based on the span setting. Coupled functions are affected depending on how they are coupled.
Instrument Functions: A - L Auto Couple • • • • • • NOTE VBW/RBW ratio is set to 1.0 Span/RBW ratio is set to Auto Auto Sweep Time is set to Normal FFT & Sweep is set to Auto: Best Dynamic ADC Ranging is set to Autorange Marker Count, Gate Time is set to Auto Marker Trace Range and Printer have an Auto setting, but are not affected by Auto All. Remote Command: :COUPle ALL|NONE :COUPle? Remote Command Notes: sets all the functions to the manual (not coupled) mode.
Instrument Functions: A - L Auto Couple Remote Command: [:SENSe]:SWEep:TYPE:AUTO:RULes SPEed|DRANge selects the rules to use when SWE:TYPE AUTO is selected. This setting, combined with your current analyzer setup, is used to select either FFT or swept mode. [:SENSe]:SWEep:TYPE:AUTO:RULes? Example: SWEep:TYPE AUTO selects the automatic mode. SWE:TYPE:AUTO:RUL DRAN sets the rules for the auto mode to dynamic range. 2.1.2.
Instrument Functions: A - L Auto Couple 2.1.2.4 Manual: FFT Manually selects FFT analysis, so it cannot change automatically to swept. While Zero Span is selected, this key is greyed out. The status of the FFT & Swept selection is saved when entering zero span and is restored when leaving zero span.
Instrument Functions: A - L Auto Couple 2.1.2.5 FFTs/Span Displays and controls the number of FFT segments used to measure the entire Span. This key is inactive (greyed out) unless Sweep Type has been set to FFT. If Sweep Type is set to Auto and FFTs are selected, FFTs/Span is still greyed out, and the number of FFTs automatically selected is shown. If Sweep Type is set to Manual:FFT, FFTs/Span becomes available. Press FFTs/Span and an integer can be entered.
Instrument Functions: A - L Auto Couple Remote Command: [:SENSe]:SWEep:FFT:SPAN:RATio [:SENSe]:SWEep:FFT:SPAN:RATio? Example: 2.1.3 SWE:FFT:SPAN:RAT 20 PhNoise Opt Selects the LO (local oscillator) phase noise behavior for various operating conditions. The selected value is displayed below the £(f) indicator on the left side of the screen. It is preceded by # if PhNoise Opt Auto has been selected.
Instrument Functions: A - L Auto Couple 2.1.3.2 Optimize £(f) for frequencies < 50 kHz The LO phase noise is optimized for offsets less than 50 kHz from the carrier, at the expense of phase noise beyond 50 kHz offset. Key Path: Auto Couple, PhNoise Opt Remote Command: See “PhNoise Opt” on page 76. Example: 2.1.3.3 FREQ:SYNT 1 Optimize £(f) for frequencies > 50 kHz Optimizes phase noise for offsets above 50 kHz from the carrier, especially those from 70 kHz to 300 kHz.
Instrument Functions: A - L Auto Couple 2.1.5 Avg/VBW Type See Avg/VBW Type in the BW/Avg menu.
Instrument Functions: A - L Auto Couple 2.1.6 ADC Dither Access the menu to set ADC Dither to On, Off, or Auto. Key Path: Auto Couple Remote Command: [:SENSe]:ADC:DITHer[:STATe] OFF|ON|AUTO [:SENSe]:ADC:DITHer[:STATe]? Example: 2.1.6.1 :ADC:DITH OFF Auto Turns the ADC dither to automatic. It then chooses on or off according to which is most likely to be the best selection, based on the other analyzer settings such as span, resolution BW and sweep type (FFT or swept).
Instrument Functions: A - L Auto Couple Remote Command: Use [:SENSe]:ADC:DITHer[:STATe] AUTO Example: 2.1.6.2 ADC:DITH AUTO On When ADC Dither is On, the linearity of low-level signals is improved. However, the ADC dynamic range is reduced to make room for the dither. As a result, the noise floor of the analyzer is somewhat compromised. So making measurements with ADC dither on gives you better amplitude linearity, but turning ADC dither off gives you a lower noise floor (better sensitivity).
Instrument Functions: A - L Auto Couple Factory Preset: Autorange Remote Command: [:SENSe]:ADC:RANGe AUTO|NONE [:SENSe]:ADC:RANGe? Example: ADC:RANG NONE 2.1.7.1 Autorange Turns the ADC ranging to automatic which provides the best signal to noise ratio. Auto Couple All sets the ADC ranging to Autorange. Autorange is usually preferred over Bypass. Key Path: Auto Couple State Saved: Saved in Instrument State Remote Command: Example: 2.1.7.

Instrument Functions: A - L Det/Demod 2.3 Det/Demod Displays the menu keys that control parameters associated with the detector modes. 2.3.1 Detector Select a specific type of detector, or choose Auto to let the instrument select the appropriate detector for a particular measurement. When discussing detectors, it is important to understand the concept of a trace “bucket.
Instrument Functions: A - L Det/Demod Because they may not find a spectral component's true peak, neither average nor sample detectors measure amplitudes of CW signals as accurately as peak or normal, but they do measure noise without the biases of peak detection. The detector in use is indicated on the left side of the display. If the detector has been manually selected, a # appears next to it.
Instrument Functions: A - L Det/Demod 2.3.1.1 Auto The system selects normal detection as the default, but if a condition arises where a different type of detection scheme would be better utilized, the system uses the alternate scheme. For example, when in Auto mode, the Marker Noise function uses Average detection because the system determines that the average detector has a better speed/variance trade-off for noise-type signals.
Instrument Functions: A - L Det/Demod Remote Command: [:SENSe]:DETector:AUTO OFF|ON|0|1 [:SENSe]:DETector:AUTO? Example: 2.3.1.2 DET:AUTO ON Normal Displays the peak-detected level in the interval (bucket) being displayed when the signal is CW-like. If the signal is noise-like (within a bucket the signal both rose and fell), the even bucket shows the peak (maximum) within a two-bucket interval, and the odd bucket shows the negative peak (minimum).
Instrument Functions: A - L Det/Demod Example: 2.3.1.4 DET AVER Peak For each interval (bucket) in the trace, Peak detection displays the highest amplitude within the interval. Peak detection is used for CW measurements and some pulsed-RF measurements. For swept analysis, peak detection basically obtains the maximum video signal between the end of the last bucket and the start of the next one. Gain is increased to compensate for the effects of faster sweep rates, to keep the displayed value accurate.
Instrument Functions: A - L Det/Demod When Sample is selected, Samp appears on the left side of the display.
Instrument Functions: A - L Det/Demod Remote Command: See “Detector” on page 95 Example: 2.3.1.7 DET SAMP Negative Peak For each interval (bucket) in the trace, Negative Peak detection displays the lowest sample within the interval. Negative peak detection is similar to peak detection, but selects the minimum video signal. When Negative Peak is selected, NPk appears on the left side of the display.

3.1 Marker Accesses the marker control menu. If no markers are active, pressing Marker activates the currently selected marker as a normal type marker and places it at the center of the display. (This will be marker 1 if you have not previously selected a different marker.) There are five control modes for the markers: Normal (POSition) - A single marker that can be moved to any point on the trace.
Instrument Functions: M - O Instrument Functions: M - O Marker volts. For example, when the percent ratio with Y-axis units in volts is 20% (0.2), the percent ratio with Y-axis units in watts will be 4% (0.22 = 0.04). When you read the value out remotely you have to know whether you are in log (dB) or linear (percent).
• Marker functions (Marker Noise and Band/Intvl Power) - the display shows the values with units that are dependent on the function and the Y-axis units. Refer to the individual function descriptions for more details about the units used. When you read the value out remotely you have to know what the expected units are. Remote Command: :CALCulate:MARKer[1]|2|3|4:MODE POSition|DELTa|BAND|SPAN|OFF :CALCulate:MARKer[1]|2|3|4:MODE? Sets or queries the marker control mode (see parameter list above).

Returns the spacing of the markers in trace points. :CALCulate:MARKer[1]|2|3|4:X:CENTer Sets the mid point of the markers to a specific frequency with a range that matches the units of the trace on which the markers are positioned.
Instrument Functions: M - O Instrument Functions: M - O Marker Marker Trace 1, 2, or 3, or Auto. In Auto mode, the analyzer places markers on the lowest-numbered trace that is in Clear Write mode. If no trace is in Clear Write mode, it places the marker on the lowest-numbered trace in Max Hold mode. If there are none, then it uses the lowest-number trace in Min Hold mode, then in View mode. For example, if trace 1 is in view, and trace 2 is in clear write, any new marker is assigned to trace 2.
:CALCulate:MARKer[1]|2|3|4:X:READout? Example: 3.1.8.1 CALC:MARK3:X:READ TIME sets the marker 3 Readout to Time. Frequency Sets the marker readout to Frequency, displaying the absolute frequency of a normal marker or the frequency of the delta marker relative to the reference marker. Frequency readout is the default setting in non-zero spans and is not available in zero spans. Key Path: Marker, Readout Remote Command: See “Readout” on page 186 for this command. Example: 3.1.8.
Instrument Functions: M - O Instrument Functions: M - O Marker 3.1.8.4 Inverse Time Sets the marker readout to Inverse Time, displaying the reciprocal of (sweep) time between two markers. This function is only available when in both zero span and in a delta-marker modes.

3.2 Marker Fctn Access special marker functions such as frequency counting and noise markers. Factory Preset: Off Remote Command: :CALCulate:MARKer[1]|2|3|4:FUNCtion BPOWer|NOISe|OFF :CALCulate:MARKer[1]|2|3|4:FUNCtion? Example: 3.2.1 CALC:MARK:FUNC NOIS Select Marker See “Select Marker” on page 180 Remote Command: Example: 3.2.2 CALC:MARK2:STAT ON selects marker 2. Marker Noise Activates a noise marker for the selected marker.
Instrument Functions: M - O Instrument Functions: M - O Marker Fctn is displayed as a ratio (dB or %).
To guarantee accurate data for noise-like signals, a correction for equivalent noise bandwidth is made by the analyzer. The Marker Noise function accuracy is best when the detector is set to Average or Sample, because neither of these detectors will peak-bias the noise. The trade off between sweep time and variance of the result is best when Avg/VBW Type is set to Power Averaging. Auto coupling, therefore, normally chooses the Average detector and Power Averaging.
Instrument Functions: M - O Instrument Functions: M - O Marker Fctn Remote Command: See “Marker Fctn” on page 191 for the command to select the function. Example: CALC:MARK:FUNC BPOW turns on marker one as a band power marker. CALC:MARK:Y? returns the value of the Band/Intvl Power function for marker 1 (if Band/Intvl Power is ON for marker 1). 3.2.4 Function Off Turns off marker functions (Band/Intvl Power and Marker Noise). Delta markers will remain on screen.

One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) 5.1 MEASURE (Spectrum Analysis Mode) In the Spectrum Analysis mode (see the Mode key), this key displays a menu that lets you to make transmitter power measurements such as adjacent channel power, occupied bandwidth, and harmonic distortion measurements. If other modes are available and have been selected, the measurements for that particular mode will be displayed.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) Measure Commands: :MEASure:[n]? This is a fast single-command way to make a measurement using the factory default instrument settings. These are the settings and units that conform to the Mode Setup settings (e.g. radio standard) that you have currently selected.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) Fetch Commands: :FETCh:[n]? This command puts selected data from the most recent measurement into the output buffer. Use FETCh if you have already made a good measurement and you want to return several types of data (different [n] values, e.g. both scalars and trace data) from a single measurement. FETCh saves you the time of re-making the measurement.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) READ Commands: :READ:[n]? • Does not preset the measurement to the factory default settings. For example, if you have previously initiated the ACP measurement and you send READ:ACP? it will initiate a new measurement using the same instrument settings. • Initiates the measurement and puts valid data into the output buffer.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) 5.1.3 Channel Power Channel Power measures the power and power spectral density in the channel bandwidth that you specify. One marker pair on the display indicates the edges of the channel bandwidth. The center frequency, reference level, and channel bandwidth must be set by the user. For more information see “Meas Setup (Channel Power—CHP)” on page 399.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) One-Button Measurement Functions expected that the DVB-T signal to be measured will be present prior to the standard being selected. The mask will be positioned relative to the power measured in the 7.61MHz bandwidth. The pass/fail indicator will be used to determine if the input signal exceeds the mask or not.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) If the current span setting is narrower than the mask width, the mask will not be displayed and the message 10191 displayed. Increase the span to at least the mask width to display the mask. When the mask is not displayed, the pass/fail functionality will not be executed therefore no pass/fail flag will be displayed. To ensure accuracy this measurement requires a specific minimum Sweep Point to Span ratio.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) 5.1.4 Occupied BW Occupied Bandwidth integrates the power of the displayed spectrum and puts markers at the frequencies between which a selected percentage of the power is contained. The measurement defaults to 99% of the occupied bandwidth power. The power-bandwidth routine first computes the combined power of all signal responses contained in the trace.
One-Button Measurement Functions MEASURE (Spectrum Analysis Mode) will return the single scalar result specified. 5.1.5 Adjacent Channel Power—ACP Adjacent Channel Power (ACP) is a measure of the power that leaks into adjacent transmit channels. Depending on the radio standard selected from the Mode Setup menu, this measurement can run in several different modes in order to measure different types of signals. For more information see “Meas Setup (Adjacent Channel Power—ACP)” on page 351.

Programming Fundamentals SCPI Language Basics SCPI Language Basics This section is not intended to teach you everything about the SCPI (Standard Commands for Programmable Instruments) programming language. The SCPI Consortium or IEEE can provide that level of detailed information.
Programming Fundamentals SCPI Language Basics Creating Valid Commands Commands are not case sensitive and there are often many different ways of writing a particular command. These are examples of valid commands for a given command syntax: Command Syntax Sample Valid Commands [SENSe:]BANDwidth[:RESolution] The following sample commands are all identical. They will all cause the same result. • Sense:Band:Res 1700 • BANDWIDTH:RESOLUTION 1.7e3 • sens:band 1.7KHZ • SENS:band 1.7E3Hz • band 1.
Programming Fundamentals SCPI Language Basics Special Characters in Commands Special Character | Meaning A vertical stroke between parameters indicates alternative choices. The effect of the command is different depending on which parameter is selected. Example Command: TRIGger:SOURce EXTernal|INTernal|LINE The choices are external, internal, and line. Ex: TRIG:SOURCE INT is one possible command choice. [] <> A vertical stroke between keywords indicates identical effects exist for both keywords.
Programming Fundamentals SCPI Language Basics Parameters in Commands There are four basic types of parameters: booleans, keywords, variables and arbitrary block program data. OFF|ON|0|1 (Boolean) This is a two state boolean-type parameter. The numeric value 0 is equivalent to OFF. Any numeric value other than 0 is equivalent to ON. The numeric values of 0 or 1 are commonly used in the command instead of OFF or ON. Queries of the parameter always return a numeric value of 0 or 1.
Programming Fundamentals SCPI Language Basics Variable Parameters Is a positive rational number followed by optional units. The default unit is Hz. Acceptable units include: HZ, KHZ, MHZ, GHZ.

Block Program Data Some parameters consist of a block of data. Block data There are a few standard types of block data. Arbitrary blocks of program data can also be used. Is an array of rational numbers corresponding to displayed trace data. See FORMat:DATA for information about available data formats.
Programming Fundamentals SCPI Language Basics SCPI Termination and Separator Syntax A terminator must be provided when an instrument is controlled using RS-232. There are several issues to be understood about choosing the proper SCPI terminator and separator when this is the case. There is no current SCPI standard for RS-232. Although one intent of SCPI is to be interface independent, is only defined for IEEE 488 operation.

Programming Fundamentals Improving Measurement Speed Improving Measurement Speed There are a number of things you can do in your programs to make them run faster: “Turn off the display updates.” on page 511 “Use binary data format instead of ASCII” on page 512 “Minimize the number of GPIB transactions.” on page 512 “Put ADC Ranging in Bypass for FFT Measurements” on page 513 “Minimize DUT/instrument setup changes.” on page 513 “Consider using LAN instead of GPIB.
Programming Fundamentals Improving Measurement Speed Use binary data format instead of ASCII The ASCII data format is the instrument default since it is easier for people to understand and is required by SCPI for *RST. However, data input/output is faster using the binary formats. :FORMat:DATA REAL,64 selects the 64-bit binary data format for all your numerical data queries. You may need to swap the byte order if you are using a PC rather than UNIX. NORMal is the default byte order.
Programming Fundamentals Improving Measurement Speed Avoid unnecessary use of *RST. Remember that while *RST does not change the current Mode, it presets all the measurements and settings to their factory defaults. This forces you to reset your analyzer’s measurement settings even if they use similar mode setup or measurement settings. See Minimize DUT/instrument setup changes. below. (Also note that *RST may put the instrument in single measurement/sweep for some modes.
Programming Fundamentals Improving Measurement Speed Consider using LAN instead of GPIB. LAN allows faster I/O of data, especially if you are moving large blocks of data. You will not get this improved throughput if there is excessive LAN traffic (i.e. your test instrument is connected to enterprise LAN). You may want to use a private LAN that is only for your test system. Using an Option Mode: Minimize the number of GPIB transactions.
Programming Fundamentals Improving Measurement Speed Using an Option Mode: Avoid automatic attenuator setting. The internal process for automatically setting the value of the attenuator requires measuring an initial burst to identify the proper attenuator setting before the next burst can be measured properly. If you know the amount of attenuation or the signal level needed for your measurement, just set it.
Programming Fundamentals Improving Measurement Speed 1. :STATus:OPERation:EVENt? This query of the operation event register is to clear the current register contents. 2. :READ:PVT? initiates a measurement (in this example, for GSM power versus time) using the previous setup.

Programming Fundamentals Using the LAN to Control the Instrument Using Telnet to Send Commands Using telnet to send commands to your instrument works in a similar way to communicating over GPIB. You establish a connection with the instrument, and then send or receive information using SCPI commands. NOTE If you need to control the bus using “device clear” or SRQ’s, you can use SICL LAN. SICL LAN provides control of your instrument via IEEE 488.2 GPIB over the LAN.

Programming Fundamentals Using the LAN to Control the Instrument Either a hardware problem or a software problem can prevent the instrument's remote file server from communicating over the LAN. The following common problems may be encountered: Communications Not Established If you have just installed and configured the LAN interface and you have never been able to access the instrument via ftp or telnet, go directly to “Pinging the Instrument from a Computer or Workstation” on page 6-542.
Programming Fundamentals Using the LAN to Control the Instrument problems continue. Packets Routinely Lost If packets are routinely lost, proceed to the troubleshooting section in this chapter relating to your network. Problems Transferring or Copying Files If you have problems copying files out of or into the instrument, you might be experiencing timeout problems. See the previous section on “Timeout Errors.
Programming Fundamentals Using the LAN to Control the Instrument are set correctly. Cannot access the file system via ftp • If you get a "connection refused" message, try the following solutions: — If the power to the instrument was just turned on, make sure that you wait about 25 seconds before attempting the connection. • If you get a "connection timed out" message — Verify the LAN connection between your computer and the instrument.
Programming Fundamentals Using the LAN to Control the Instrument Pinging the Instrument from a Computer or Workstation Verify the communications link between the computer and the instrument remote file server using the ping utility. From a UNIX workstation, type: ping hostname 64 10 where 64 is the packet size, and 10 is the number of packets transmitted.

Standard straight-through patch cables can then be used from the instrument to the adapter, and from the adapter to other LAN devices. If you use a special-purpose adapter, you will avoid having a cross-over cable mistaken for a standard, straight-through patch cable.
Programming Fundamentals Programming in C Using the VTL Programming in C Using the VTL The programming examples that are provided are written using the C programming language and the Agilent VTL (VISA transition library). This section includes some basic information about programming in the C language. Note that some of this information may not be relevant to your particular application. (For example, if you are not using VXI instruments, the VXI references will not be relevant).
Programming Fundamentals Programming in C Using the VTL language. The viPrintf call sends the IEEE 488.2 *RST command to the instrument and puts it in a known state. The viPrintf call is used again to query for the device identification (*IDN?). The viScanf call is then used to read the results. viClose This function must be used to close each session. When you close a device session, all data structures that had been allocated for the session will be de-allocated.

You can close the specific device session, which will free all data structures that had been allocated for the session. If you close the default resource manager session, all sessions opened using that resource manager will be closed.
Programming Fundamentals Overview of the GPIB Bus Overview of the GPIB Bus An instrument that is part of a GPIB network is categorized as a listener, talker, or controller, depending on its current function in the network. Listener A listener is a device capable of receiving data or commands from other instruments. Any number of instruments in the GPIB network can be listeners simultaneously. Talker A talker is a device capable of transmitting data or commands to other instruments.
Programming Fundamentals Overview of the GPIB Bus • A clear function that causes all GPIB instruments, or addressed instruments, to assume a cleared condition. The definition of clear is unique for each instrument (sometimes called: clear, reset, control, send). • An output function that is used to send function commands and data commands from the controller to the addressed instrument (sometimes called: output, control, convert, image, iobuffer, transfer).

Using the STATus System Using the STATus System When you are programming the instrument you may need to monitor instrument status to check for error conditions or monitor changes. You can determine the state of certain instrument events/conditions by programming the status register system. IEEE common commands (those beginning with *) access the higher-level summary registers. To access the information from specific registers you would use the STATus commands.
Status System Commands IEEE (*) Commands *CAL? Calibration Query *CLS Clear Status *ESE , *ESE? Standard Event Status Enable *ESR? Standard Event Status Register Query *IDN?

Operation Complete *OPC *OPC? The *OPC command sets bit 0 in the standard event status register to “1” when pending operations have finished. It does not hold off subsequent operations. The *OPC? query stops new commands from being processed until the current processing is complete.
Using the STATus System Using the STATus System Common IEEE Commands Power-On Status Clear *PSC *PSC? Sets the state of the power-on status clear flag. This command allows you to specify if the service request enable register and the event status enable register should be cleared at power up. The query returns the contents of the power-on status clear flag. Key Type: There is no equivalent front panel key.
*RST does not change the mode and only resets the parameters for the current mode. The :SYSTem:PRESet command is equivalent to a front panel Preset key. Save *SAV This command saves the instrument state to the specified instrument memory register. Key Type: There is no equivalent front panel key.
Using the STATus System Using the STATus System Common IEEE Commands Trigger *TRG This command triggers the instrument. Use the :TRIGger[:SEQuence]:SOURce command to select the trigger source. If you have selected a one-button measurement and it has been paused (INITiate:PAUSe), or the CONFigure: command was used. The command causes the system to exit this “waiting” state and go to the “initiated” state. The trigger system is initiated and completes one full trigger cycle.
