Example
SweepILinMeasureV(smua, -1E-3, 1E-3, 0, 100)
This function performs a 100-point linear current
sweep starting at
−
1 mA and stopping at
+
1 mA.
Voltage is measured at every step (point) in the
sweep. Because
stime
is set for 0 s, voltage is
measured as quickly as possible after each
current step.

SweepIListMeasureV()
This KISweep factory script function performs a current list sweep with voltage measured at every step (point).

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
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 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
testilist = {-100E-9, 100E-9, -1E-6, 1E-6,
-1E-3, 1E-3}
SweepIListMeasureV(smua, testilist,
500E-3, 6)
This function performs a six-point current list
sweep starting at the first point in
testilist
.
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.
