If a digital pin is configured as the trigger source, the instrument will wait indefinitely for the trigger
signal. If the trigger does not occur, you must manually return the trigger system to the idle state. The
following commands return the trigger system to the idle state:
Front Panel Menu Reference
Select Transient\Control.
Then select the Abort control.
When a trigger is received, the triggered functions are set to their programmed transient values. When
the triggered actions are completed, the trigger system returns to the idle state.
You can test the TRAN-active bit in the Operation Status register to know when the transient trigger
system has returned to the idle state.
Front Panel Menu Reference
Select Transient\Control.
The Trig state field indicates "Idle".
If a bit value of 64 is returned in the query, the TRAN-active bit is true, and the transient action is NOT
complete. When the TRAN-active bit is false, the transient action is complete. Refer to
for more information.

Program the step Level
Use the following commands to program the triggered output step level. The output will go to this level
when the trigger is received. In the front panel menu, you can only program the step level based on the
priority mode that you are operating in - voltage or current priority.
