Example
trigger.timer[1].stimulus = smua.trigger.IDLE_EVENT_ID Trigger timer 1 when the SMU
returns to the idle layer.

smuX.trigger.initiate()
This function initiates a sweep operation.
Type TSP-Link accessible

Function
Yes
Usage
smu
X
.trigger.initiate()
X
Source-measure unit (SMU) channel (for example,
smua.trigger.initiate()
applies to SMU channel A)
Details
This function causes the SMU to clear the four trigger model event detectors and enter its trigger model (moves
the SMU from the idle state into the arm layer).
To perform source actions during the sweep, before calling this function, it is necessary to configure and enable
one of the following sweep source actions:
•
smu
X
.trigger.source.linear
Y
()
•
smu
X.
trigger.source.list
Y
()
•
smu
X
.trigger.source.log
Y
()
To perform measurements during the sweep, you must also configure and enable the measure action using
smu
X
.trigger.measure.
Y
()
.
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; use the
bufferVar
.clearcache()
function to
remove stale values from the reading buffer cache.
This function initiates an overlapped operation.
Example
smua.trigger.initiate()
Starts a preconfigured sweep and
clears the event detectors for SMU
channel A.
