Function:
SweepILinMeasureV(smu, starti, stopi, stime, points)
Description: Performs a linear current sweep with voltage measured at every step (point):
Parameters:
Data: Voltage measurements, current source values and timestamps are stored in

• Sets the to output
smu
seconds and then performs a voltage measurement.
stime
• Sets the to output the next amps step, allows the source to settle for
smu
seconds and then performs a voltage measurement.
stime
• Repeats the above sequence until the voltage is measured on the
amps step.
The linear step size is automatically calculated as follows:

SweepILinMeasureV(smua, -1E-3, 1E-3, 0, 100)
This function performs a 100-point linear current sweep starting at -1mA and
stopping at +1mA. Voltage is measured at every step (point) in the sweep.
Since is set for 0s, voltage will be measured as fast as possible after
