Details
If any parameters are omitted or nil, the operator will be prompted to enter them using the front panel.
Data for pulsed current measurements, voltage levels, and timestamps are stored in smuX.nvbuffer1.
Performs a specified number of pulse V, measure I cycles:
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

Current measurement
Example 1
smua.measure.nplc = 0.001
PulseVMeasureI(smua, -1, 1, 1E-3, 2E-3, 20)
SMU A will output -1 V and dwell for 2 ms,
output 1 V and dwell for 1 ms. The current
measurement occurs during the dwell
period. After the measurement, the output
will return to -1 V and dwell for 2 ms. This
pulse-measure process will repeat 19 more
times.
