range
The pulser current range to adjust

cp2Reference
The reference measurement for point 2 as measured externally
Details
This function generates and activates new calibration constants for the given range.
Typically, the two points that are used are near zero for point 1 and 90% of full scale for point 2. Full
scale for point 2 should be avoided if the source of the SMU is substantially out of calibration.
The new calibration constants are activated immediately but they are not written to nonvolatile
memory. Use the smua.cal.save() function to save the new constants to nonvolatile memory. The
active calibration constants stay in effect until the instrument is power cycled or a calibration set is
loaded from nonvolatile memory with the smua.cal.restore() function.
This function is only available when calibration is unlocked using smua.cal.unlock().
Example
smua.pulser.source.calibratei(1, 1e-10, 1e-5, 0.9, 0.903)
Generates and activates new source calibration constants for the pulser 1 A range. For point 1, it uses 1e−10
as the source value and 1e−5 as the reference measurement. For point 2, it uses 0.9 for the source value and
0.903 for the reference measurement.
