Details
Data for pulsed voltage measurements are stored in the reading buffer specified by the
buffer
input parameter.
This function configures a linear 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
step
amperes larger than the previous pulse, where:
step = (stop - start) / (points - 1)
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.

Set up a pulsed sweep that will use System

®
instrument channel A. The pulsed
sweep will start at 10 mA, end at 50 mA, and return to
a 0 mA bias level between pulses. Each pulsed step
will be on for 15 ms, and then at the bias level for
100 ms. The voltage limit will be 500 V during the
entire pulsed sweep. The pulse train will be
comprised of 20 pulsed steps and the pulse train will
be assigned a tag index of 3.
