4 Using the Solar Array Simulator
68 Series E4360 User’s Guide
If you need the curve lists to closely follow external events, the lists can
be paced by external trigger signals. With trigger-pacing, the lists
advance one curve for each trigger received. Select a trigger source from
the available trigger sources. With a trigger-paced list, you do not need
to program a dwell time for each curve.
All lists must have the same number of parameter values, otherwise an
error will occur when the lists are run. For convenience, a parameter list
may be programmed with only one value. In this case, the single-value
list is treated as if it had the same number of values as the other lists,
with all parameters in the list set to the same value.
The following table illustrates the differences between programming the
list data from the front panel or using SCPI commands. The rows
illustrate how five curves are programmed using the SCPI parameter
commands. The columns illustrate how five curves are programmed
using the front panel list steps.

NOTE
List data is not stored in non-volatile memory. This means that any list
data that is sent to the SAS will be lost when the unit is powered off.
