Usage
SweepIListMeasureV(
smu, ilist, stime, points
)
smu
System SourceMeter
®
instrument channel (set to
smua
)
ilist
Arbitrary list of current source values;
ilist = {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 voltage measurements, current 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 current list sweep with voltage measured at every step (point):
1. Sets
the
smu
to output
ilist
amperes value, allows the source to settle for
stime
seconds, and
then performs a voltage measurement.
2. Sets
the
smu
to output the next
ilist
step, allows the source to settle for
stime
seconds, and
then performs a voltage measurement.
3. Repeats the above sequence until the voltage is measured for the last amperes value. The last
point in the list to be measured is
points
.
Example
myilist = {-100E-9, 100E-9, -1E-6, 1E-6,
-1E-3, 1E-3}
SweepIListMeasureV(smua, myilist,
500E-3, 6)
This function performs a six-point current list sweep
starting at the first point in
myilist
. Voltage 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
SweepILogMeasureV()
(on page 5-22) function performs a logarithmic current sweep with voltage measured
at every step (point).
