Network Analyzer is equipment widely used for the execution of radio frequency application scattering parameters. Throughout absolute reading the scattering parameter measured. An absolute reading does not include error, drift, offset, linearity, resolution, coefficient of sensitivity and several other variables that will contribute to the measured measurement dispersion. Type A evaluations of measurement uncertainty clarified according to ISO / IEC Guide 98-1. Type A uncertainty assumption is

The assumption was calculated from arithmetic mean, variance of probability distribution and standard deviation respected to the frequency from 300 kHz to 8.5 GHz in a Network Analyzer measurements. Furthermore, ISO/IEC 17025 is the standard for accredited testing and calibration laboratory to calculate the uncertainty of measurement to be declared in the scope of accreditation. Type A uncertainty calculation is one of the mandatory requirements for an accredited testing and calibration laboratory. The Type A uncertainty will be combined with Type B uncertainty to calculate the expanded uncertainty in measurement.
