Example program usage
The functions in this script allow the parameters of the test to be adjusted without rewriting and
rerunning the script. To execute the test, either call
CapturePulseV()
to capture a voltage pulse or
CapturePulseI()
to a capture current pulse, passing in the appropriate values as parameters.
Both of these functions capture both current and voltage. The difference between the functions is
what they are sourcing — one sources voltage, and the other sources current.
The parameters of the
CapturePulseV()
function are described in the following table:
CapturePulseV() parameters
Parameter
Units
Description
pulseLevel
Volts
The voltage level of the pulse
pulseWidth
Seconds
The width of the pulse
pulseLimit
Amperes
The current limit of the pulses to output
numPulses
Not applicable
The number of pulses to output
An example call to this function is as follows:
CapturePulseV(10, 300e-6, 50, 5)
This call will output five 10 V pulses with a 300
µ
s pulse width. The pulses will be limited to 50 A and
have a 1 percent duty cycle. At the completion of the pulsed outputs, the source-measure unit (SMU)
output is turned off. The resulting data from this test will be returned in a Microsoft
®
Excel
®
compatible
format (you can cut and paste the output from the console) that can be used for graphing and
analysis.
The parameters of the
CapturePulseI()
function are contained in the following table:
CapturePulseI() parameters
