| Abstract: | In accordance with the measurement problem of phase noise of frequency modulation wave raised in cesium atomic clock system, a measurement was made with HP 3048A phase noise measurement system. On the basis of analyzing the measurement results, we derive a mathematic model for phase noise of frequency modulation wave and gave the verification of it through experiments. The conclusion shows that the theory is consistent with experiment. As a result the method of measuring the phase noise of frequency modula- tion wave is put forward. |
