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 SCPI Command
Select Transient\Control .
Then select the Abort control.
ABOR:TRAN
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 SCPI Command
Select Transient\Control .
The Trig state field indicates "Idle".
To query the TRAN-active bit (bit 6):
STAT:OPER:COND?
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
Status Tutorial
for more information.
Programming a Step Transient
Program the Step Levels
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.
Front Panel Menu Reference SCPI Command
Select Transient\Step .
Select the Trig Voltage box to set the voltage. Select the
Trig Current box to set the current. Enter a value and
press Select.
To set a voltage step level of 15 V use:
VOLT:TRIG 15
To set a current step level of 1 A use:
CURR:TRIG 1
Generate a Trigger Out Signal
The output step can generate a trigger signal that can be routed to a pin on the digital port that has
been configured as a trigger output (TOUT). Use the following commands to generate a trigger signal
when the step occurs:
Front Panel Menu Reference SCPI Command
Select Transient\Step .
Check Enable Trigger Output. Then press Select .
To program a Step trigger signal, use:
STEP:TOUT ON
