The phase detecting error caused by local oscillator frequency drift and non-synchronization of measurement signal and gate signal is eliminated and the measurement speed is improved at the same time.
The process of attenuation measurement is presented, which utilizes a system consisted of a sweep oscillator, a pair of broad-banded horns, and a scalar network analyzer, etc.
