Abstract
To measure frequency stability of 10.23MHz signal, a 10.2299MHz frequency source based on AD9854 was developed. The performance of frequency source was tested using a phase noise and Allan deviation test set 5125A. According to the experiment results, the following conclusion can be drawn that the Allan deviation of the 10.2299MHz frequency signal is about 2.6E-14 at 1s when the 10MHz reference signal was generated by a frequency and phase offset generator HROG-10. The 10.2299MHz frequency source can be used as a common source in dual mixer time difference and as a reference signal in beat frequency method when measuring the frequency stability of 10.23MHz signal.
