Error Terms
The analyzer generates and stores factors in internal arrays when a measurement
error-correction (measurement calibration) is performed. These factors are known by the
following terms:
• error terms
• E-terms
• measurement calibration coefficients
The analyzer creates error terms by measuring well-defined calibration devices over the
frequency range of interest and comparing the measured data with the ideal model for the
devices. The differences represent systematic (repeatable) errors of the analyzer system.
The resulting calibration coefficients are good representations of the systematic error
sources. For details on the various levels of error-correction, refer to the "Optimizing
Measurement Results" chapter of your analyzer's user's guide. For details on the theory of
error-correction, refer to the "Operating Concepts" chapter of your analyzer's user's guide.
