Details
If any parameters are omitted or nil, the operator is prompted to enter them using the front panel.
Data for pulsed current measurements, voltage levels, and timestamps are stored in
smuX.nvbuffer1.
To perform the specified number of pulse V, measure I cycles, this function:
1. Sets the smu to output bias volts and dwell for toff seconds
2. Sets the smu to output level volts and dwell for ton seconds
3. Performs voltage measurement with source at level volts
4. Sets the smu to output bias volts for toff seconds
5. Repeats steps 2 through 4 for the remaining points pulse-measure cycles

Example
smua.measure.nplc = 0.001
PulseVMeasureI(smua, -1, 1, 1E-3, 2E-3, 20)
SMU A outputs −1 V and dwells for 2 ms,
outputs 1 V and dwells for 1 ms. The current
measurements occur during each 1 ms
dwell period. After the measurement, the
output returns to −1 V and dwells for 2 ms.
This pulse-measure process repeats 19
more times.
