Example

trigger.timer[1].stimulus = smua.trigger.IDLE_EVENT_ID

Trigger timer 1 when the SMU

returns to the idle layer.

Triggering (on page 3-32)

smuX.trigger.initiate()

This function initiates a sweep operation.

Type TSP-Link accessible

Affected by Where saved Default value

Function

Yes

Usage

smuX.trigger.initiate()

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:

• smuX.trigger.source.linearY()

• smuX.trigger.source.listY()

• smuX.trigger.source.logY()

To perform measurements during the sweep, you must also configure and enable the measure action

using smuX.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.
