Sweep Operation
smuX.trigger.source.listY()
This function configures an array-based source sweep.
Type TSP-Link accessible
Function Yes
Usage
smuX.trigger.source.listY(sweepList)

Y
sweepList
Details
This function configures the source action to be a list sweep in a subsequent sweep. During the sweep, the
source will output the sequence of source values given in the sweepList array.
If the subsequent sweep has more points than specified in sweepList, the source will restart at the beginning.
This means that if the trigger count is greater than the number of points in a sweep as configured, the SMU will
satisfy the trigger count by restarting the sweep values from the beginning.
If the subsequent sweep has fewer points than specified in sweepList, the extra values will be ignored. This
means that if the trigger count is less than the number of source values configured, the SMU will satisfy the
trigger count and ignore the remaining source values.
In cases where the first sweep point is non-zero, it may be necessary to pre-charge the circuit so that the sweep
will return a stable value for the first measured point without penalizing remaining points in the sweep.
The SMU will only store the most recent configured source action. The last call to
smuX.trigger.source.linearY(), smuX.trigger.source.listY(), or
smuX.trigger.source.logY() is used for the source action.
Source functions cannot be changed within a sweep.
After configuring the sweep source values, enable the source action by setting
smuX.trigger.source.action.
