ST2883 Series Operation Manual                              Chapter 8 SCPI Command reference 

8-16 

NOTE: The :TRIGger[:IMMediate] command starts a measurement of standard waveform and ST2883 

returns the standard waveform data directly without receiving the FETCh SWAVE? command. In SEQ 
CYCLE mode, ST2883 returns standard waveform data when each sampling test is completed. In ONE 
CYCLE mode, ST2883 returns the last standard waveform, and returns the standard waveform when 
sample rate is changed.

 

 
The :CHOose command is used to select the required standard waveform. 
Command syntax: SWAVE:CHOose 
For example: WrtCmd( “SWAVE:CHO” )

；

 

 NOTE:    1. This command is available only on <MEAS DISP> page. 

2. This command is valid only when sampling  test  is  finished  in  SEQ  CYCLE  mode  or  ONE 

CYCLE mode.
