TRIGger
The TRIGger command subsystem controls the behavior of the trigger system
once it is initiated (see INITiate command subsystem). The trigger command
subsystem controls:
•
The delay between trigger and first Pacer pulse (TRIG:DELay)
•
An immediate software trigger (TRIG:IMM)
•
The source of the trigger (TRIG:SOUR BUS| EXT| HOLD| IMM)
Subsystem Syntax TRIGger
:DELay < delay>
:DELay? [MIN | MAX]
[:IMMediate]
:SLOPe < slope>
:SLOPe?
:SOURce BUS | EXT | HOLD | IMM
:SOURce?
:DELay TRIGger:DELay < delay> sets the delay between receipt of trigger and first
Pacer pulse.

*RST Condition: TRIG:DELay 2.5E-9
Example Setting delay between trigger and Pacer output.
TRIG:SOUR HOLD trigger is TRIG command
SOUR:PULS:COUN 100 set Pacer to output 100 pulses
SOUR:PULS:PER .1 S pulse period set to .1 second
TRIG:DELAY .75 S start Pacer .75 sec after trigger
INIT go to Wait For Trigger state
TRIG trigger Pacer to output pulses
:DELay? TRIGger:DELay? [ MIN | MAX] returns:
•
The current delay if no parameter is sent.
•
The maximum allowable delay if MAX is sent.
•
The minimum allowable delay if MIN is sent.
Example Querying the trigger delay setting.
TRIG:DEL .75 S start Pacer .75 sec after trigger
TRIG:DEL? command System Instrument
to send TRIG:DEL value.
enter statement input value of trigger delay
