Title

Automated Q-Factor Measurement Via a Network Analyzer

Author

Abstract

An algorithm is developed for the HP automated network analyzer that can determine the three basic parameters of microwave cavity resonators: the unloaded resonant frequency fo, the unloaded Q-factor Q_o, and the coupling coefficient β. The input reflection coefficient of the resonator is measured via the network analyzer, which is driven by an HP desk computer. The graphical techniques (Smith Chart) are replaced by the much faster calculations on the computer using numerical techniques. Stirling and Bessel’s formulas, in conjunction with the central difference interpolation method, are used to interpolate between sampled points to enhance the accuracy of the algorithm.

Experimental results are compared against theoretical calculations for different cavities to support the validity of the algorithm.
