Indeed a nice post, as usual for Andrew.

The 16 bit ADCs (at least the LTC lower sample rate ones ) tend to be a few
dBc/Hz quieter.
However the difference is < 12 dBc/Hz.

Hi
I just found Andrew recently post a phase noise measruement page on
www.aholme.co.uk/PhaseNoise/Main.htm .
He uses 4-channel 14bit ADC to do the sampling work. -170dBc noise floor seems
not bad for me.
Since the cross correlation could reduce noise a lot, I am wondering what the
