4 Using the Regenerative Power System
Specify the list pacing
You can specify if the list will be dwell or trigger-paced. The default selection is dwell-paced.
In a dwell paced list, each step is assigned a dwell time. The dwell time determines the time that the
output remains at the step. As each dwell time elapses, the next step is immediately output.
In a trigger-paced list, the list advances one step for each trigger received. You can also specify a dwell
period if you want to ignore triggers during the dwell time, or guarantee a minimum dwell time
between triggered list steps.
Front Panel Menu Reference
Select Transient\List\Pace.
Select either Dwell paced or Trigger paced. Then press
Select.
Specify any trigger signals that the list should generate
You can generate trigger signals that can be routed to other destinations. For example, you can use
trigger signals to trigger actions on any external equipment connected to the digital port. The
following figure gives an example of generating four trigger signals on the voltage list of Example 2.
Front Panel Menu Reference
Select Transient\List\Config.
Select the List Step number 4. To generate a trigger,
enter a 1 in the Tout Begin Step field.
Select the List Step numbers 0, 2, and 4. To generate a
trigger, enter a 1 in the Tout End Step field.
If zeroes are entered in the fields, no trigger is
generated for the step.
Specify how many times you want the list to repeat
You can specify how many times you want the list (or pulse) to repeat. At reset, the list count is set to
one repetition. Sending the INFinity parameter in the SCPI command makes the list repeat indefinitely.
Front Panel Menu Reference
Select Transient\List\Repeat.
Enter the number of list repetitions (2) and press
Select.

SCPI Command
To set the list pacing to dwell-paced:
LIST:STEP AUTO
To set the list pacing to trigger-paced:

SCPI Command
To program a trigger at the beginning of step 4:
LIST:TOUT:BOST 0,0,0,0,1,0
To program a trigger at the end of step 0, 2, and 4:
