current pulse train

Define the pulse test parameters
The following pulse test parameters, which define the magnitude and timing of the pulse, are used in
this example application. The actual values for these test parameters will vary depending on your
specific application.
Test parameter Value Definition
biaslevel
0 A
Sets the offset current of the pulse
train.
pulselevel
6 A
Sets the amplitude current of each
pulse from zero (not from bias
level).
biaswidth
3e-3 s
Sets the time at the bias level.
pulsewidth
1e-3 s
Sets the time at the amplitude level
for each pulse.
period
pulsewidth + biaswidth
Specifies the amount of time it
takes for the pulse to repeat itself
(calculated value in this example
resolves to 4 ms).
points
10
Sets the total number of pulses to
generate.
limit
7 V
Sets the source limit level.
measuredelay
pulsewidth -((1/localnode.linefreq)
*smu.measure.nplc + 450e-6)
Specifies the amount of time that
the pulse remains at the pulse level
before the measurement is taken.
The value 450e-6 is overhead
associated with converting a raw
measurement into a reading.
