triggerCount
The trigger count is the number of times the source-measure unit (SMU) will iterate
in the trigger layer for any given sweep
X
SMU channel (for example,
smua.trigger.count
applies to SMU channel A)
Details
During a sweep, the SMU iterates through the trigger layer of the trigger model this many times. After performing
this many iterations, the SMU returns to the arm layer.
If this count is set to zero (
0
), the SMU stays in the trigger model indefinitely until aborted.
