Output Lists
Output current, voltage, power, and resistance may be list-controlled. For Models N678xA SMU, only
the parameters associated with one of the priority modes may be list controlled. Power and
Resistance lists only apply to Models N679xA loads. List mode lets you generate complex sequences
of output changes with rapid, precise timing, which may be synchronized with internal or external
signals. Lists can contain up to 512 individually programmed steps, and can be programmed to repeat
themselves.
The current, voltage, power, and resistance lists are paced by a separate list that defines the duration
or dwell of each step. Each of the up to 512 steps can have an individual dwell time associated with it,
which specifies the time in seconds that the list will remain at that step before moving on to the next
step. Dwell times can be programmed from 0 to 262.144 seconds. The default dwell time is 0.001
seconds.
If you need an output list to closely follow external events, then a trigger-paced list is more
appropriate. In a trigger-paced list, the list advances one step for each trigger received. As previously
discussed, a number of trigger sources can be selected to generate triggers. With a trigger-paced list,
you do not need to program a dwell time for each step. If you do program a dwell time, triggers that
are received during the dwell period are ignored.
Lists can also be configured to generate trigger signals at specified steps. This is accomplished by two
additional lists: a beginning-of-step (BOST) and an end-of-step (EOST) list. These lists define which
steps will generate a trigger signal and if the trigger occurs at the beginning or end of the step. These
trigger signals can be used to synchronize other events with the list.
When either a voltage, current, power, or resistance list is programmed, the associated dwell, BOST,
and EOST lists must all be set to the same number of steps, otherwise an error will occur when the list
is run. For convenience, a list may be programmed with only one step or value. In this case, a single-
step list is treated as if it had the same number of steps as the other lists, with all values being equal
to the one value.
