Command Syntax You can control the operations and functions of the oscilloscope through the Ethernet port or the USB 2.0 device port using commands and queries. The related topics listed below describe the syntax of these commands and queries. The topics also describe the conventions that the oscilloscope uses to process them. See the Command Groups topic in the table of contents for a listing of the commands by command group, or use the index to locate a specific command.
Command Syntax Table 2-2: Command Message Elements Commands Symbol Meaning This is the basic command name. If the header ends with a question mark, the command is a query. The header may begin with a colon (:) character. If the command is concatenated with other commands, the beginning colon is required. Never use the beginning colon with command headers beginning with a star (*). This is a header subfunction. Some command headers have only one mnemonic.
Command Syntax Queries Queries cause the oscilloscope to return status or setting information. Queries have the structure: [:] [:][ []...] You can specify a query command at any level within the command tree unless otherwise noted. These branch queries return information about all the mnemonics below the specified branch or level. Headers Use the HEADer command to control whether the oscilloscope returns headers as part of the query response.
Command Syntax Clearing the oscilloscope You can clear the Output Queue and reset the oscilloscope to accept a new command or query by using the selected Device Clear (DCL) function. Command Entry The following rules apply when entering commands: You can enter commands in upper or lower case. You can precede any command with white space characters.
Command Syntax When concatenating commands and queries, you must follow these rules: 1. Separate completely different headers by a semicolon and by the beginning colon on all commands except the first one. For example, the commands TRIGger:MODe NORMal and ACQuire:NUMAVg 8, can be concatenated into the following single command: TRIGger:MODe NORMal;:ACQuire:NUMAVg 8 2.
Command Syntax Table 2-4: End of Message Terminator Symbol Meaning Message terminator The end-of-message terminator must be the END message (EOI asserted concurrently with the last data byte). The last data byte may be an ASCII line feed (LF) character. This oscilloscope does not support ASCII LF only message termination. The oscilloscope always terminates outgoing messages with LF and EOI. Constructed Mnemonics Some header mnemonics specify one of a range of mnemonics.
Command Syntax Measurement Specifier Mnemonics Commands can specify which measurement to set or query as a mnemonic in the header. Up to four automated measurements may be displayed. Table 2-8: Measurement Specifier Mnemonics Symbol Meaning MEAS A measurement specifier; is 1 through 4. Channel Mnemonics Commands specify the channel to use as a mnemonic in the header. Reference Waveform Mnemonics Commands can specify the reference waveform to use as a mnemonic in the header.
Command Syntax Table 2-11: Quoted String Argument Symbol Meaning Quoted string of ASCII text A quoted string can include any character defined in the 7-bit ASCII character set. Follow these rules when you use quoted strings: 1. Use the same type of quote character to open and close the string. For example: "this is a valid string". 2. You can mix quotation marks within a string as long as you follow the previous rule. For example: "this is an 'acceptable' string". 3.

Command Groups NOTE.
Command Groups Each data value requires two to seven characters. This includes one to five characters to represent the value, another character, if the value is negative, to represent a minus sign, and a comma to separate the data points. An example ASCII waveform data string may look like this: CURVE-110,-109,-110,-110,-109,-107,-109,-107,-106, -105,-103,-100,-97,-90,-84,-80 NOTE. You can use ASCII to obtain a readable and easier to format output than binary.
Command Groups command. Next, specify the first data point within the waveform record. For example, when you set DATa:STARt to 1, data points will be stored starting with the first point in the record. The oscilloscope will ignore the value set by DATa:STOP when reading in data. It will stop reading data when there is no data to read or when it has reached the specified record length. When transferring data from the oscilloscope, you must specify the first and last data points in the waveform record.
Command Groups Transferring Waveform Data to the Oscilloscope You can transfer waveforms to the oscilloscope from an external controller using the following sequence: 1. Specify the reference waveform using DATa:DESTination. 2. Specify the record length of the reference waveform using WFMPre:NR_Pt. 3. Specify the waveform data format using WFMInpre:ENCdg. 4. Specify the number of bytes per data point using WFMInpre:BYT_Nr. 5. Specify first data point in the waveform record using DATa:STARt. 6.

Status and Events The oscilloscope provides a status and event reporting system for the Ethernet, GPIB (with the TEK-USB-488 Adapter), and USB interfaces. This system informs you of certain significant events that occur within the oscilloscope. The oscilloscope status handling system consists of five 8-bit registers and two queues for each interface. The remaining Status subtopics describe these registers and components. They also explain how the event handling system operates.
Status and Events Table 3-1: SESR Bit Functions Bit Function 7 (MSB) PON Power On. Shows that the oscilloscope was powered on. On completion, the diagnostic self tests also set this bit. 6 URQ User Request. Indicates that an application event has occurred. *See note. 5 CME 4 EXE Command Error. Shows that an error occurred while the oscilloscope was parsing a command or query. Execution Error. Shows that an error executing a command or query. 3 DDE Device Error.
Status and Events Table 3-2: SBR Bit Functions (cont.) Bit Function 4 MAV Message Available. Shows that output is available in the Output Queue. 2 ———— Not used. ———— Not used. 1–0 ———— Not used. 3 Enable Registers DESER, ESER, and SRER allow you to select which events are reported to the Status Registers and the Event Queue.
Status and Events Use the *SRE command to set the SRER. Use the *SRE? query to read the register. The RQS bit remains set to one until either the Status Byte Register is read with a Serial Poll or the MSS bit changes back to a zero. Figure 3-5: The Service Request Enable Register (SRER) *PSC Command The *PSC command controls the Enable Registers contents at power-on.
Status and Events Read the Event Queue with the EVENT? query (which returns only the event number), with the EVMSG? query (which returns the event number and a text description of the event), or with the ALLEV? query (which returns all the event numbers along with a description of the event). Reading an event removes it from the queue. Before reading an event from the Event Queue, you must use the *ESR? query to read the summary of the event from the SESR.
Status and Events Figure 3-6: Status and Event Handling Process When an event occurs, a signal is sent to the DESER (1). If that type of event is enabled in the DESER (that is, if the bit for that event type is set to 1), the appropriate bit in the SESR is set to one, and the event is recorded in the Event Queue (2). If the corresponding bit in the ESER is also enabled (3), then the ESB bit in the SBR is set to one (4). When output is sent to the Output Queue, the MAV bit in the SBR is set to one (5).
Status and Events Synchronization Methods Overview Although most commands are completed almost immediately after being received by the oscilloscope, some commands start a process that requires time. For example, once a single sequence acquisition command is executed, depending upon the applied signals and trigger settings, it may take an indeterminate amount of time before the acquisition is complete.
Status and Events For example, a typical application might involve acquiring a single-sequence waveform and then taking a measurement on the acquired waveform.
Status and Events The same command sequence using the *WAI command for synchronization looks like this: /* Set up conditional acquisition */ ACQUIRE:STATE OFF SELECT:CH1 ON ACQUIRE:MODE SAMPLE ACQUIRE:STOPAFTER SEQUENCE /* Acquire waveform data */ ACQUIRE:STATE ON /* Set up the measurement parameters */ MEASUREMENT:IMMED:TYPE AMPLITUDE MEASUREMENT:IMMED:SOURCE CH1 /* Wait until the acquisition is complete before taking the measurement */ *WAI /* Take amplitude measurement */ MEASUREMENT:IMMED:VALUE? The c
Status and Events many commands to the input buffer. The controller is still tied up though, and the repeated BUSY? query will result in bus traffic. Using the *OPC Command If the corresponding status registers are enabled, the *OPC command sets the OPC bit in the Standard Event Status Register (SESR) when an operation is complete. You achieve synchronization by using this command with either a serial poll or service request handler.
Status and Events The same command sequence using the *OPC command for synchronization looks like this /* Set up conditional acquisition */ ACQUIRE:STATE OFF SELECT:CH1 ON ACQUIRE:MODE SAMPLE ACQUIRE:STOPAFTER SEQUENCE /* Enable the status registers */ DESE 1 *ESE 1 *SRE 32 /* Acquire waveform data */ ACQUIRE:STATE ON /* Set up the measurement parameters */ MEASUREMENT:IMMED:TYPE AMPLITUDE MEASUREMENT:IMMED:SOURCE CH1 /* Wait until the acquisition is complete before taking the measurement*/ *OPC The progr
Status and Events /* Wait until the acquisition is complete */ *OPC? /* Take amplitude measurement */ MEASUREMENT:IMMED:VALUE? This is the simplest approach. It requires no status handling or loops. However, you must set the controller time-out for longer than the acquisition operation.

Appendix B: Waveform Data in MSO/DPO2000B and MSO/DPO2000 Series Instruments An analog channel of an MSO/DPO2000B and MSO/DPO2000 series instrument has a sample waveform and a peak detect waveform being acquired simultaneously. This combination waveform is referred to as a “composite” waveform. In some cases, for example when averaging is turned on, or for math waveforms, a composite waveform is not available. In these cases, the waveform is termed “singular”, and is available only in sample mode.
Appendix B: Waveform Data in MSO/DPO2000B and MSO/DPO2000 Series Instruments Composition of Waveform Data The MSO/DPO2000/B series introduces the concept of composite waveform data for analog channels. Sample data is always available for acquired analog channel waveforms. Composite waveforms are available in SAMPLE acquisition mode but are not available in AVERAGE acquisition mode.
Appendix B: Waveform Data in MSO/DPO2000B and MSO/DPO2000 Series Instruments COMPOSITE_YT COMPOSITE_YT, COMPOSITE_ENV SINGULAR_YT The composition of the waveform data to be queried using the CURVe? or WAVFrm? queries is set using the DATa:COMPosition or WFMOutpre:COMPosition command.
Appendix B: Waveform Data in MSO/DPO2000B and MSO/DPO2000 Series Instruments reduced resolution waveform. The filtering frequency of the full resolution waveform is not under your direct control. It is a function of the horizontal and acquisition settings and the selected FilterVu frequency. The 3 dB cutoff frequency for this filtering may be different for the LRL record and the thumbnail record.
Appendix B: Waveform Data in MSO/DPO2000B and MSO/DPO2000 Series Instruments Querying Acquisition Peak Detect Data from the Instrument 1. Use the DATa:COMPosition:AVAILable? query to determine if peak detect data (COMPOSITE_ENV) is available. This query returns a list of waveform data types that are available from the instrument under the current instrument settings: COMPOSITE_YT for sample data COMPOSITE_ENV for envelope or peak detect data SINGULAR_YT for sample data 2.
