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
1 0.25
2 0.25
3 0.25
4 0.25
5 0.25

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.
