Section 7: Command reference

Example

smuX.trigger.initiate()

This function initiates a sweep operation.
Type TSP-Link accessible
Function Yes
Usage
smuX.trigger.initiate()
X
Details
This function causes the SMU to clear the four trigger model event detectors and enter its trigger model state
machine (moves the SMU from the idle state into the arm layer).
To perform source actions during the sweep, it is necessary to configure and enable one of the sweep source
actions, smuX.trigger.source.linearY(), smuX.trigger.source.listY(), or
smuX.trigger.source.logY(), and measure actions (smuX.trigger.measure.Y(), prior to calling this
function.
If you run this function more than once without reconfiguring the sweep measurements, the caches on the
configured measurement reading buffers will hold stale data. If you do run this function repeatedly without
reconfiguring the sweep measurement, use the bufferVar.clearcache() function to remove stale values
from the reading buffer cache.
This function initiates an overlapped operation.
