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
.

Set up a pulsed logarithmic sweep that uses System
SourceMeter
®
instrument channel A. The pulsed
sweep starts at 1 V, ends at 10 V, and returns to a
0 V bias level between pulses. Each pulsed step is on
for 10 ms, and then at the bias level for 20 ms.
The current limit will be 1 A 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 6.
