X
Source-measure unit (SMU) channel (for example,
smua.trigger.arm.count
applies to SMU channel A)
Details
During a sweep, the SMU iterates through the arm layer of the trigger model this many times. After
performing this many iterations, the SMU returns to an idle state.
If this count is set to zero, the SMU stays in the trigger model indefinitely until aborted.
Example
smua.trigger.arm.count = 5
Sets the SMU channel A to iterate through the arm layer of the trigger model five times and then return to the
idle state.

smuX.trigger.arm.set()
This function sets the arm event detector to the detected state.

Usage
smu
X
.trigger.arm.set()
X
Source-measure unit (SMU) channel (for example,
smua.trigger.arm.set()
applies to SMU channel A)
Details
The SMU automatically clears all the event detectors when the
smu
X
.trigger.initiate()
function is executed. This function should be called after the sweep is initiated.
A common example of when this function can be used is when you want the SMU to immediately
perform an action the first time through the trigger model even if a programmed trigger event does not
occur.
This function can also be used to start actions on the SMU in case of a missed trigger event.
