7-330 2651A-901-01 Rev. A / March 2011
Usage
SweepVListMeasureI(smu, vlist, stime, points)
smu
System SourceMeter
®
instrument channel (set to smua)
vlist
Arbitrary list of voltage source values; vlist = {value1, value2, ...
valueN}
stime
Settling time in seconds; occurs after stepping the source and before performing a
measurement
points
Number of sweep points (must be ≥2)
Details
Data for current measurements, voltage source values, and timestamps are stored in smuX.nvbuffer1.
If all parameters are omitted when this function is called, this function is executed with the parameters set to the
default values.
Performs a voltage list sweep with current measured at every step (point):
1. Sets the smu to output vlist volts value, allows the source to settle for stime seconds, and
then performs a current measurement.
2. Sets the smu to output the next vlist volts value, allows the source to settle for stime seconds,
and then performs a current measurement.
3. Repeats the above sequence until the current is measured for the last volts value. The last point
in the list to be measured is points.
Example
myilist = {-0.1, 0.1, -1, 1, -6, 6, -40,
40, 0, 0}
SweepVListMeasureI(smua, myvlist,
500E-3, 10)
This function performs a 10-point voltage list sweep
starting at the first point in myvlist. Current is
measured at every step (point) in the sweep. The
source will be allowed to settle on each step for
500 ms before a measurement is performed.

None
SweepVLogMeasureI()
This KISweep factory script (on page 5-22) function performs a logarithmic voltage sweep with current measured
at every step (point).
