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.

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
smu
X
.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
