Study on the test method for a frequency converter with an embedded local oscillator in satellite

Beginning with the test demand of frequency converter with embedded local oscillator in satellite, this paper, combining the technical feature of multifunctional vector network analyzer, puts forward a precise test method, which is based on frequency tracking and vector mixer calibration technique regarding the test requirement of group delay and conversion loss of frequency converter with embedded local oscillator. Through the result, we can see that the test method is accurate, feasible and can provide effective technical measures for the performance testing and evaluation of the frequency converter with embedded local oscillator in satellite.
