Details
This function is useful whenever you want the SMU to continue operation without waiting for a programmed
trigger event. When called, this function immediately satisfies the event detector, allowing the SMU to continue
through the trigger model.
For example, you might use this function to have the SMU immediately perform an action the first time through
the trigger model, even if a programmed trigger event does not occur.
If the event detectors are configured to clear automatically because the
smu
X
.trigger.autoclear
attribute is
set to
smu
X
.ENABLE
, make sure that
smu
X
.trigger.measure.set()
is issued after the SMU has entered
the trigger layer. This function can also be used to start actions on the SMU in case of a missed trigger event.
The SMU automatically clears all event detectors when the
smu
X
.trigger.initiate()
function is executed.
This function should be called after the sweep is initiated.
Example
smua.trigger.measure.set()
Sets the measure event detector of
SMU channel A.
