[time-nuts] An example of phase noise

Thought this might be interesting.  I took a spectrum analyzer shot of
my ICS525 "Clock-Block" synthesizer at 250MHz, and overlaid it with a
shot of an RF signal generator (Marconi 2202A) at the same frequency,
and using the same reference source.

The 2202A is designed for bench use and isn't noted for particularly
good phase noise, but you can see the dramatic difference between the
two units (the ICS525 is in red, the 2202A in cyan).

That's why the Clock-Block isn't recommended for RF use!
