KIGeneral TSP test script: SweepIListMeasureV
Function:
Description Performs a current list sweep with voltage measured at every step (point):
• Sets the smu to output the first ilist amps value, allows the source to
settle for
stime seconds and then performs a voltage measurement.
• Sets the smu to output the next ilist amps value, allows the source to
settle for
stime seconds and then performs a voltage measurement.
• Repeats the above sequence until the voltage is measured for the last
amps value. The last point in the list to be measured is
points.
Parameters
smu, ilist, stime, points
smu: SourceMeter Channel (A or B). Defaults to SMU A if all
parameters are omitted when function is called.
ilist: Arbitrary list of current source values:
ilist = {value1, value2, ....valueN}
stime: Settling time in seconds. Occurs after sourcing a value and before
performing a measurement.
points: Number of sweep measure points (must be ≥2).
Data
Voltage measurements, current source values and timestamps are stored in
smuX.nvbuffer1.
Example
myilist = {-100E-9, 100E-9, -1E-6, 1E-6, -1E-3, 1E-3}
SweepIListMeasureV(smua, myilist, 500E-6, 6)
This function performs a 6-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 value for 500µs before a measurement is performed.
Example SweepVLogMeasureI(smua, 1, 10, 0.001, 5)
This function performs a 5-point logarithmic voltage sweep starting at 1V and
stopping at 10V. Current is measured at every step (point) in the sweep. The
source will be allowed to settle on each step for 1ms before a measurement is
performed.
The following log values and corresponding source levels for the 5-point log
sweep are listed as follows:
MeasurePoint LogStepSize LogStep SourceStepLevel
1 0.25 0.0 1.0000V
2 0.25 0.25 1.7783V
3 0.25 0.5 3.1623V
4 0.25 0.75 5.6234V
5 0.25 1.0 10.000V
