Example
SweepVLogMeasureI(smua, 1, 10,
0.001, 5)
This function performs a five-point logarithmic voltage
sweep starting at 1 V and stopping at 10 V. Current is
measured at every step (point) in the sweep after a 1 ms
source settling period.
The following table contains log values and corresponding
source levels for the five-point logarithmic sweep:

LogStepSize LogStep SourceStepLevel
1 0.25 0.0 1.0000 V
2 0.25 0.25 1.7783 V
3 0.25 0.5 3.1623 V
4 0.25 0.75 5.6234 V
