[time-nuts] Re: Low Phase Noise 10 MHz bench signal source sought

[Mike Monett]

Joseph,

You will find it difficult to get below -170 dBc/Hz. However, you can use
cross-correlation to get as low as -220 dBc/Hz.

Rubiola is a wealth of information on cross-correlation. You can download
his papers at

See "The cross-spectrum experimental method, February 2010"
