EISA bus.
C

calibration
The process of determining the accuracy of an instrument. In a formal
sense, calibration establishes the relationship of an instrument's
measurement to the value provided by a standard. When that relationship is
known, the instrument may then be adjusted (calibrated) for best accuracy.
calibrator
A precise, traceable signal source used to calibrate instruments.
