Details
Data for pulsed voltage measurements are stored in the reading buffer specified by the buffer input parameter.
This function configures a logarithmic pulsed current sweep with a voltage measurement at each point.
Measurements are made at the end of the ton time.
The magnitude of the first pulse will be start amperes; the magnitude of the last pulse will be stop amperes.
The magnitude of each pulse in between will be LogStep
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. The
InitiatePulseTest(tag) and InitiatePulseTestDual(tag1, tag2) functions are used to initiate a
pulse train assigned to a valid tag.

Set up a pulsed logarithmic sweep that uses System
®
SourceMeter instrument channel A. The pulsed
sweep will start at 1 mA, end at 10 mA, and return to
a 0 A bias level between pulses. Each pulsed step
will be on for 1 ms, and then at the bias level for 10
ms. The voltage limit will be 1 V during the entire
pulsed sweep. The pulse train will be comprised of 10
pulsed steps, and the pulse train will be assigned a
tag index of 5.
