Keithley 2461 Reference Manual

Model 2461
Interactive SourceMeter® Instrument Reference Manual Section 8:

The name of the source configuration list determines the name of the measure configuration list;
Meas is appended to the beginning of the name. If the name of your configuration list is greater than
28 characters, it is truncated to include only the first 28 characters (including the prefix Meas that is
added for the measure configuration list). For example, if the source configuration list is named
VoltagePulseLinearSweepList (27 characters), the resulting measure configuration list is
named MeasVoltagePulseLinearSweepList (31 characters). If the source configuration list is
named MyLongPulseNameSweepConfigList (30 characters), the resulting measure configuration
list is MeasMyLongPulseNameSweepConfigLi (32 characters).
Example
reset()
smu.source.func = smu.FUNC_DC_CURRENT
smu.source.range = 3
smu.source.readback = smu.OFF
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.range = 10
smu.measure.autozero.enable = smu.OFF
smu.measure.nplc = .01
smu.source.pulsesweeplinearstep("CurrPulseLinSweepList",0 ,-3, 3, .25, 10e-3,
smu.ON, defbuffer1, 0, 100e-3, 1, 10, 10, smu.OFF, smu.OFF)
trigger.model.initiate()
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 .01.
Set up a linear pulse step sweep 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 pulse sweep.
