Abstract
PURPOSE:The signal corresponding to local oscillation frequency signal is applied to local oscillation circuit, and the frequency signal of the sum or difference of the signal corresponding to local transmission frequency signal and intermediate frequency signal is supplied to antenna resonance circuit to perform a measurement. In this way, effects of local oscillation circuit is eliminated as well as accuracy of the measurement is increased.
