triggerArmCount
The arm count in the trigger model.
X
SMU channel (for example,
smua.trigger.arm.count
applies to SMU Channel
A).
Details
During a sweep, the SMU will iterate through the arm layer of the trigger model this many times. After performing
this many iterations, the SMU will return to idle.
If this count is set to zero, the SMU will stay 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.

Default value
Function Yes
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 will automatically clear 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.
