[time-nuts] How to measure phase noise of HCMOS oscillators?

A while a go i bought some low phase noise Crystek CVHD-950 and now I want
to meas the phase noise of the oscillators.
Is it best to try to impedance match the output signal and filter and
amplify the hcmos before i feed it in to the phase detector? or Just hope
that the signal is high enough to drive the mixer? What about all the
harmonics? Does it alter the phase noise result?
