TH2883 Series Operation Manual Chapter 8 SCPI Command reference
8-28
Query syntax: WaveSTEP: WaveMODE ?
The query returns: <mode><NL^END>
<mode> is as follows: NONE This step does not have any settings
SAMPLE This step is the standard wave sampling mode.
SW.COPY This step is the standard wave copy mode.
TW.COPY This step is a comparison test mode
The :STEP command is used for step copying or comparison test step selection; the :STEP?
command querys the step in Standard Copy or Contrast Test.
Command syntax: WaveSTEP:STEP [stepdirection]
[stepdirection] is as follows:
UP If the mode is a standard copy or comparison test, it means that the previous step
matches, and the other modes cannot use UP.
DOWN If the mode is a standard copy or comparison test, it means matching to the next step.
Other modes cannot use DOWN.
For example: WrtCmd("WaveSTEP:STEPUP" ); returns the previous step of copying or comparing
the standard.
Query syntax: WaveSTEP: WaveMODE ?
The query returns: <step><NL^END>
<step> is as follows: STD.Step_XX Standard copy copy step number.
TST.Step_XX Compare test step numbers.
Note: XX in STD.Step_XX represents the step number.
8.3.15 Common commands
TH2883 provides following common commands:
*RST
The *RST command is used to reset the instrument.
Command syntax: *RST
For example: WrtCmd( “*RST” );
*TRG
The *TRG command (trigger command) triggers a measurement and writes the tested waveform
data into the output buffer. This command is equal to TRIG+FETCh TWAVE? command.
Command syntax: *TRG?
For example: WrtCmd( “*TRG?” );
NOTE:
This command is only available on the <MEAS DISP> pages. This command will
also be ignored when TH2883 is in the testing state. This command is only used to trigger a
measurement except for sampling a standard waveform. Refer to Standard WAVE Subsystem
