LIST:VOLTage 120, 100, 110
LIST:FREQuency 60, 60, 60
Step 3 : Determine the time interval that the output remains at each level or point in the list
before it advances to the next point. The time is specified in seconds. For example, to
specify five dwell intervals, use:
LIST:DWELl 1, 3.5, 1.5, 0.5, 3.8, 1.2
The number of dwell points must equal the number of output points. If a dwell list has only
one value, that value will be applied to all points in the output list.
Step 4 : Determine the number of times the list is executed before it completes. For
example, to run a list 10 times use:
LIST:COUNt 10
At *RST, the count is set to 1.
Step 5 : Determines how the list sequencing responds to triggers. For a closely controlled
sequence of output levels, you can use a dwell-paced list. To cause the list to be paced by
dwell time use:
LIST:STEP AUTO
As each dwell time elapses, the next point is immediately output. This is also the *RST
setting.
If you need the output to closely follow asynchronous events, then a trigger-paced list is
more appropriate. In a trigger-paced list, the list advances one point for each trigger
received. To enable trigger-paced lists use:
LIST:STEP ONCE
The dwell time associated with each point determines the minimum time that the output
remains at that point. If a trigger is received before the previous dwell time completes, the
trigger is ignored. Therefore, to ensure that no triggers are lost, program the dwell time
minimum.
Step 6 : Use the transient trigger system to trigger the list. This is described in detail under
“Triggering Output Changes”
