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
smu
X
.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, -50, 125, 10e-3, 20e-3,
10)
SMU A outputs
−
50 V and dwells for 10 ms,
outputs 125 V and dwells for 20 ms. The
current measurement occurs during the
dwell period. After the measurement, the
output returns to
−
50 V and dwells for
10 ms. This pulse-measure process repeats
9 more times.
