Series 2600 System SourceMeter® Instruments Reference Manual
Parameters
smu, bias, level, ton, toff, points
smu:
SourceMeter Channel (A or B). Defaults to SMU A if all parameters are
omitted when function is called.
bias:
Bias level in volts.
level:
Pulse level in volts.
ton:
Pulse on-time in seconds.
toff:
Pulse off-time in seconds.
points:
Number of pulse-measure cycles.
Data
Pulsed current measurements, voltage levels and timestamps are stored in
smuX.nvbuffer1
.
Example
PulseVMeasureI(smub, -1, 1, 1E-3, 2E-3, 20)
SMU B will output -1V and dwell for 1ms, output 1V and dwell for 2ms, and then
perform a current measurement. After the measurement, the output will return to -
1V and dwell for 2ms. This pulse-measure process will repeat 19 more times.

1.0.2 and later
Function:
SweepILinMeasureV(smu, starti, stopi, stime, points)
Description
Performs a linear current sweep with voltage measured at every step (point):
• Sets the
smu
to output
starti
amps, allows the source to settle for
stime
seconds, and then performs a voltage measurement.
• Sets the
smu
to output the next amps step, allows the source to settle for
stime
seconds, and then performs a voltage measurement.
• Repeats the above sequence until the voltage is measured on the
stopi
amps step.
The linear step size is automatically calculated as follows:
step = (stopi – starti) / (points – 1)
starti
= Voltage measurement
stopi
