Define the pulse sweep test parameters
The following pulse parameters, which define the magnitude and timing of the pulse sweep, will be
entered into the pulse command to generate the configuration list and trigger model necessary for the
pulses. The actual values for these test parameters will vary depending on your specific application.
Test parameter
Value
Definition
configListName
myPulseSweep
The name of the configuration list that contains the pulse
values created by the pulse command.
biaslevel
0 V
Sets the offset voltage of the pulse sweep.
start
0 V
Sets the starting value of the pulse sweep.
stop
4.15 V
Sets the ending value of the pulse sweep.
pulsewidth
0.8 ms
Sets the time at the amplitude level for each pulse.
measureEnable
smu.ON
Enables measurements at the top of each pulse. Turning this
feature off makes the instrument source pulses without
measuring.
bufferName
defbuffer1
Sets the buffer in which the measurement data will be stored.
delay
0 ms
Sets the delay before each pulse.
offTime
19 ms
Sets the time at the bias level.
count
1
Sets the number of times the sweep is repeated.
xBiasLimit
1 A
Sets the current limit between pulses when the bias level of
the voltage is sourced.
xPulseLimit
10 A
Sets the current limit during the pulse when the pulse level of
voltage is sourced.
failAbort
smu.OFF
Abort the pulse sweep if bias or pulse source limit is
exceeded.
Dual
smu.OFF
If enabled, sets the pulses to sweep back to the starting
value.
