Sweepvlistmeasurei() - Keithley 2651A Reference Manual

Model 2651A High Power System SourceMeter® Instrument Reference Manual
Details
Data for current measurements, voltage source values, and timestamps are stored in smuX.nvbuffer1.
If all parameters are omitted when this function is called, this function is executed with the parameters set to the
default values.
Performs a linear voltage sweep with current measured at every step (point):
1. Sets the smu to output startv amperes, allows the source to settle for stime seconds, and then
performs a current measurement.
2. Sets the smu to output the next amperes step, allows the source to settle for stime seconds, and
then performs a voltage measurement.
3. Repeats the above sequence until the voltage is measured on the stopv amperes step.
The linear step size is automatically calculated as follows:
step = (stopv – startv) / (points – 1)

This function performs a 1000-point linear
voltage sweep starting at -1 V and stopping at
+1 V. Current is measured at every step (point)
in the sweep after a 1 ms source settling period.
