Notice how the 10811 sits in its own little quiet space airflow-wise.

Once the buffer-board has it's 10 MHz presence detector disabled, you 
could measure the phase-noise of the 10811 on the 10 MHz output.

You could compare that with the result of the same 10811 sitting on the 
quiet bench (keep it covered by a small box).

Cheers,
