METHOD AND DEVICE FOR DETERMINING SIDEBAND RATIO OF SUPERCONDUCTION MIXER USING COMB GENERATOR

摘要

A method for determining the sideband ratio of a superconduction mixer using a comb generator. The method is characterized in that (a) the sideband ratio of a mixer for correction of the output of a comb generator is tentatively adjusted, (b) the intensity of a signal of a pseudo−celestial body signal oscillator for correction of the output of a comb generator, (c) steps (a), (b) are repeated to derive the relation between the sideband ratio and the intensity of the pseudo−celestial body signal, (d) the comb generator output is corrected, and (e) the sideband ratio of the mixer to be measured is derived.
