Series 2600A System SourceMeter® Instruments Reference Manual Section 19: Remote Commands
Parameters
smu, starti, stopi, stime, points
smu: SourceMeter instrument Channel (A or B). Defaults
to SMU A if all parameters are omitted when function
is called.
starti: Sweep start current in amps.
stopi: Sweep stop current in amps.
stime: Settling time in seconds. Occurs after stepping the
source and before performing a measurement.
points: Number of sweep points (must be ≥2).
Data
Voltage measurements, current source values and timestamps are stored in
smuX.nvbuffer1.
Example
SweepILinMeasureV(smua, -1E-3, 1E-3, 0, 100)
This function performs a 100-point linear current sweep starting at -1mA and
stopping at +1mA. Voltage is measured at every step (point) in the sweep. Since
stime is set for 0s, voltage will be measured as fast as possible after each
current step.

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