Details
Set the stimulus of any trigger event detector to the value of this constant to have it respond to idle events from
this SMU.
Example
trigger.timer[1].stimulus =
smua.trigger.IDLE_EVENT_ID
Trigger timer when the SMU
returns to the idle layer.

smuX.trigger.initiate()
This function initiates a sweep operation.

Usage
smu

.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 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,
smu
X
.trigger.source.linear
Y
()
,
smu
X
.trigger.source.list
Y
()
, or
smu
X
.trigger.source.log
Y
()
, and measure actions (
smu
X
.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.
Example
smua.trigger.initiate()
Starts a preconfigured sweep and
clears the event detectors for SMU
channel A).
