[time-nuts] Crosscorrelation phase noise measurements

Hi,

I've heard and read some documents about using cross-correlation using
two distinct reference oscillators when trying to measure the phase
noise from a source to reduce the influence of the reference
oscillators phase noise.

Unfortunately, it's still not exactly clear to me how it works ...
does anyone have a concrete example maybe with data and the exact math
that was done on them to get the result ?

Cheers,

    Sylvain
