smuX.contact.calibratehi()
This function calibrates the high/sense high contact check measurement. This function is not available on the
Models 2604B/2614B/2634B.
Type TSP-Link accessible
Affected by Where saved Default value
Usage
smuX.contact.calibratehi(cp1Measured, cp1Reference, cp2Measured, cp2Reference)
Source-measure unit (SMU) channel (for example,
smua.contact.calibratehi() applies to SMU channel A)
The value measured by this SMU for calibration point 1
The reference measurement for calibration point 1 as measured externally
The value measured by this SMU for calibration point 2
The reference measurement for calibration point 2 as measured externally
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 calibration set that is active. If not, corruption of the calibration constants may
result.
The new calibration constants are activated immediately but are not written to nonvolatile memory.
Use smuX.cal.save() 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 smuX.cal.restore() function.
This function will be disabled until a successful call to smuX.cal.unlock() is made.
