Description
Set date when the adjustment was done.
Set calibration date (calDate of 0 indicates date not set).
Set date when calibration should be performed (calDue of 0
indicates date not set).
Performs calibration adjustment of the fast analog-to-digital
converter (ADC).
Lock out calibration.
Change password to "newPassword".
Set polarity:
smua.CAL_AUTO (automatic polarity).
smua.CAL_NEGATIVE (negative polarity).
smua.CAL_POSITIVE (positive polarity).
Load set of calibration constants:
smua.CALSET_NOMINAL (nominal constants).
smua.CALSET_FACTORY (factory constants).
smua.CALSET_DEFAULT (normal constants).
smua.CALSET_PREVIOUS (previous constants).
Store constants in nonvolatile memory as DEFAULT
calibration set.
Request calibration state:
smua.CALSTATE_CALIBRATING
smua.CALSTATE_LOCKED
smua.CALSTATE_UNLOCKED
Unlock calibration (default password: KI0026XX)
