Measurement Accuracy
Any precision measurement is no better than the calibration of the network
analyzer. As a general rule, the shorter the time between a calibration and the
measurement of a device under test (DUT), the more precise the
measurement will be, within the limitations of your system. For this reason,
Agilent recommends that for precision measurements you recalibrate your
system every few hours, or at a minimum, reverify your system calibration.
The frequency of your required calibration will depend on the temperature
stability of the location of the network analyzer.
