  • Higher-phase noise measurement method using frequency prescaler, an apparatus and a program using the method
    Publication number: 20060209942
    Abstract: Signals under test are subjected to frequency division before being input to a phase detector by a method for measuring the phase noise of signals under test using an apparatus for measuring phase noise comprising a phase detector. Moreover, the level of the output of the phase detector is multiplied by N times, or the level of the results of spectrum analysis of the output of the phase detector is collectively multiplied by N times, with N being the ratio of frequency division.
