The magnitude of the first pulse is start amperes; the magnitude of the last pulse is stop amperes.
The magnitude of each pulse in between is LogStep
n
amperes larger than the previous pulse,
where:
LogStepSize = (log10(stop) - log10(start)) / (points -1)
LogStepn = (n - 1) * (LogStepSize), where n = [2, points]
SourceStepLeveln = antilog(LogStepn) * start
This function does not cause the specified smu to output a pulse train. It simply checks to see if all of
the pulse dimensions can be achieved, and if they can, assigns the indicated tag or index to the
pulse train. To initiate a pulse train assigned to a valid tag, use InitiatePulseTest(tag) and
InitiatePulseTestDual(tag1, tag2).

Set up a pulsed logarithmic sweep that uses channel A. The pulsed sweep starts at 1 mA, ends at 10 mA, and
returns to a 0 A bias level between pulses. Each pulsed step is on for 1 ms, and then at the bias level for 10
ms. The voltage limit is 1 V during the entire pulsed sweep. The pulse train is comprised of 10 pulsed steps,
and the pulse train is assigned a tag index of 5.
