Details
Set this attribute to zero (0) to disable the automatic trigger output.
Do not use the stimulus attribute for generating output triggers under script control. Use
digio.trigger[N].assert() instead.
Trigger stimulus for a digital I/O line may be set to one of the existing trigger event IDs, described in the following
table.
Trigger event IDs*
Event ID
smuX.trigger.SWEEPING_EVENT_ID
smuX.trigger.ARMED_EVENT_ID
smuX.trigger.SOURCE_COMPLETE_EVENT_ID
smuX.trigger.MEASURE_COMPLETE_EVENT_ID
smuX.trigger.PULSE_COMPLETE_EVENT_ID
smuX.trigger.SWEEP_COMPLETE_EVENT_ID
smuX.trigger.IDLE_EVENT_ID
digio.trigger[N].EVENT_ID
tsplink.trigger[N].EVENT_ID
lan.trigger[N].EVENT_ID
display.trigger.EVENT_ID
trigger.EVENT_ID
trigger.blender[N].EVENT_ID
trigger.timer[N].EVENT_ID
* Use the name of the trigger event ID to set the stimulus value rather than the numeric value. Using the name
makes the code compatible for future upgrades (for example, if the numeric values must change when
enhancements are added to the instrument).
Example 1
digio.trigger[3].stimulus = 0
Example 2
digio.trigger[3].stimulus =
smua.trigger.SOURCE_COMPLETE_EVENT_ID
