smuX.contact.calibratehi()

This function calibrates the high/sense high contact check measurement.
Type TSP-Link accessible
Function Yes
Usage
smuX.contact.calibratehi(cp1Measured, cp1Reference, cp2Measured, cp2Reference)
X
cp1Measured
cp1Reference
cp2Measured
cp2Reference
Details
Contact check measurement calibration does not require range information.
Typically, calibration points one and two will be near 0 Ω and 50 Ω, respectively.
All four measurements (cp1Measured, cp1Reference, cp2Measured, and cp2Reference) must be made
with the active calibration set. If not, corruption of the calibration constants may result.
The new calibration constants will be activated immediately but are not written to nonvolatile storage. Use
smuX.cal.save() to save the new constants to nonvolatile storage. The active calibration constants will stay in
effect until the instrument is power cycled or a calibration set is loaded from nonvolatile storage with the
smuX.cal.restore() function.
This function will be disabled until a successful call to smuX.cal.unlock() is made.
