Details
This command is similar to a serial poll, but it is processed like any other instrument command.
The *STB? command returns the same result as a serial poll, but the master summary bit (MSB) is
not cleared if a serial poll has occurred. The MSB is not cleared until all other bits feeding into the
MSB are cleared.

Type Affected by Where saved Default value
Command only Not applicable Not applicable Not applicable
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 3-131).
