Maintaining Measurement Accuracy

Precision measurements rely on a precision calibration of the network

analyzer. As a general rule, the shorter the time lapse between a calibration

and a device measurement, the more precise the measurement results will be

(within the limitations of your system).

Hewlett-Packard recommends calibrating your system every few hours, or at

least re-verifying your system’s calibration this frequently. Doing so helps

retain measurement precision.

The frequency of calibrations is determined by both the location of the

system and the ambient temperature stability in its operating area.
