Set up a pulsed logarithmic sweep that uses
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
10ms. 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.

ConfigPulseVMeasureI()
(on page 5-23) function configures a voltage pulse train with a current measurement at
each point.
