at each point. Measurement(s) will be made at the end of the ton time. The
magnitude of the first pulse will be start amps. The magnitude of the last
pulse will be stop amps. The magnitude of each pulse in between will be
amps larger than the previous pulse where:

LogStepSize =(log10(stop) - log10(start)) / (points -1)
= (n - 1) x (LogStepSize) where n = [1, points]

This function does not cause the specified smu to output a pulse train. It
simply checks to see if all of the pulse dimensions are achievable and if so,
assigns the indicated tag or index to it. The InitPulseTest(tag) and
InitPulseTestDual(tag) functions are used to initiate a pulse train
assigned to a valid tag.
