SCPI command reference
2461-901-01 A/November 2015 6-115
When you specify a delay, a delay block is added to the pulse sweep trigger model. This delay is
added to any source delay you may have set. For example, if you set 10 ms for the source delay and
25 ms for the delay in the pulse log sweep command, the actual delay is 35 ms.
This command updates a source configuration list named CurrPulseLinearSweepList or
VoltPulseLinearSweepList, depending on the source function.
If measurements are enabled, this command creates a measure configuration list named
MeasCurrPulseLinearSweepList or MeasVoltPulseLinearSweepList, depending on the
source function.

INIT
Reset the instrument to its default settings.
Set the source function to current and the source range to 3 A.
Turn source readback off.
Set the measure function to voltage and the measure range to 10 V.
Turn off autozero and set the NPLC to 0.01.
Set up a linear pulse step sweep that sweeps from -3 A to 3 A in 250 mA steps. Set the pulse width to 10 ms,
the off time to 100 ms, and the bias level to 0 A.
Start the sweep.
