Figure 119: SweepVLinMeasureI()
Example
SweepVLinMeasureI(smua, 500, 3000, 15e-3,
26)
This function performs a 26-point linear voltage
sweep starting at 500 V and stopping at 3000 V.
Current is measured at every step (point) in the
sweep after a 15 ms source settling period.

SweepVListMeasureI()
This KISweep factory script function performs a voltage list sweep with current measured at every step (point).
Type TSP-Link accessible
Affected by Where saved Default value
Function No
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.
