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

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.
