RESUMO

The development results of hardware computing system (HCS) for measurement of resonators characteristics with Q-factor values from dozens of units up to hundred thousand within the frequency bandwidth from 26 GHz to 37.5 GHz are provided. The measurements are based on recording and processing of amplitude-frequency characteristics (AFC) of resonators. The method for calculation of loaded Q-factor, resonant frequency, relative amplitude of oscillations and level of the constant component of the signal, as well as the shift of phases between them on factors of approximation of the resonator AFC by fractional-rational function are suggested. It is shown, how using the factors of approximation of AFC of the reflection coefficient from the resonator the eigen Q-factor and the share of signal scattering power in a coupling element can be calculated. The results of tests demonstrating the system capabilities at studying the resonators with low‐ and high‐quality factors are presented.
