Details
Data for pulsed current measurements are stored in the reading buffer specified by the buffer input
parameter.
This function configures a logarithmic pulsed voltage sweep with a current measurement at each
point. Measurements are made at the end of the ton time.
The magnitude of the first pulse will be start volts; the magnitude of the last pulse will be stop
volts. The magnitude of each pulse in between will be LogStep
n
volts larger than the previous pulse,
where:
LogStepSize = (log10(stop) - log10(start)) / (points -1)
LogStep
n
= (n - 1) * (LogStepSize), where n = [2, points]
SourceStepLevel
n
= antilog(LogStep
n
) * start
This function does not cause the specified smu to output a pulse train. It does check to see if all the
pulse dimensions can be achieved, and if they can, assigns the indicated tag or index to the pulse
train. The InitiatePulseTest(tag) and InitiatePulseTestDual(tag1, tag2) functions
are used to initiate a pulse train assigned to a valid tag.
