Type Affected by Where saved Default value
Command only
Usage
*TRG
Details
Use the *TRG command to generate a trigger event.
If you are using the SCPI command set, this command generates the COMMAND event. If you are using the
TSP command set, this command generates the trigger.EVENT_COMMAND event. You can use this constant
as the stimulus of any trigger object, which causes that trigger object to respond to the trigger events generated
by *TRG. See Using trigger events to start actions in the trigger model (on page 3-109
).
