Usage
PulseIMeasureV(
smu, bias, level, ton, toff, points
)
smu
System SourceMeter
®
instrument channel (for example,
smua
refers to SMU
channel A)
bias
Bias level in amperes
level
Pulse level in amperes
ton
Pulse on time in seconds
toff
Pulse off time in seconds
points
Number of pulse-measure cycles
Details
Data for pulsed voltage measurements, current levels, and timestamps are stored in
smua.nvbuffer1.
If any parameters are omitted or
nil
, the operator is prompted to enter them using the front panel.
To perform the specified number of pulse I, measure V cycles, this function:
1. Sets the
smu
to output
bias
amperes and dwell for
toff
seconds.
2. Sets the
smu
to output
level
amperes and dwell for
ton
seconds.
3. Performs voltage measurement with source at
level
amperes.
4. Sets the
smu
to output
bias
amperes for
toff
seconds.
5. Repeats steps 2 through 4 for all remaining
points
pulse-measure cycles.

Example
PulseIMeasureV(smua, 0.001, 1.0,
20e-3, 40e-3, 10)
SMU A outputs 1 mA and dwells for 40 ms, outputs
1 A and dwells for 20 ms. The voltage measurements
occur during each 20 ms dwell period. After the
measurement, the output returns to 1 mA and dwells
for 40 ms. This pulse-measure process repeats nine
more times.
