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()
t
(on page 5-22) function performs a logarithmic voltage sweep with current measured
at every step (point).
