smuX.trigger.count
This attribute sets the trigger count in the trigger model.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes SMU reset
Instrument reset
Recall setup
Not saved 1
Usage
triggerCount = smuX.trigger.count
smuX.trigger.count = triggerCount
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.

Usage
pulseAction = smuX.trigger.endpulse.action
smuX.trigger.endpulse.action = pulseAction
pulseAction
The pulse mode setting; set to one of the following values (see Details for
definition):
0 or smuX.SOURCE_IDLE
1 or smuX.SOURCE_HOLD
X
Source-measure unit (SMU) channel (for example,
smua.trigger.endpulse.action applies to SMU channel A)
Details
When set to smuX.SOURCE_HOLD, this attribute disables pulse mode sweeps, holding the source level for the
remainder of the step.
When set to smuX.SOURCE_IDLE, this attribute enables pulse mode sweeps, setting the source level to the
programmed (idle) level at the end of the pulse.
