4 Using the Regenerative Power System
Specify the Arb type and dwell
To specify the Arb type and dwell:
Front Panel Menu Reference
Select Transient\Arb\Config.
In the dropdown list, pick either a voltage or a current
Arb. Then press Select.
Enter a dwell value in the Dwell field. Then press
Select.
Configure the Arb
Note that you can use the numeric up/down arrows to view arb points in the front panel
Transient\Arb\Config dialog. You cannot program Arb data from the front panel. You must use the
SCPI ARB:CURRent:CDWell or ARB:VOLTage:CDWell commands to program the Arb data.
Front Panel Menu Reference
Select Transient\Arb\Config.
If Arb points have been imported or programmed using
the SCPI command, the Points field displays the
number of points in the Arb.
View the amplitude of any Arb point by entering the
point number in the Point # field. The Level field
displays the amplitude.
Specify how many times you want the Arb to repeat
Depending on your application, specify how many times you want the Arb to repeat. Sending the
INFinity parameter in the SCPI command makes the Arb repeat indefinitely. At reset, the Arb count is
set to 1.
Front Panel Menu Reference
Select Transient\Arb\Repeat.
Enter the number of list repetitions (2) and press
Select.
Specify how you want the Arb to end
Specify the output state after the Arb has completed. There are two choices: the output returns to the
state it was in before the Arb started, or the output remains at the values of the last Arb point.
Front Panel Menu Reference
Select Transient\Arb\Terminate.
Select either Return to Start, or Stop at Last Step and
press Select.
