I seem to remember some discussions on a lost cost test instrument,
which would give "good enough: results, on this list very recently.
That would be the sort of gadget which would allow you to compare what
ocxo devices you have. If you have a dedicated spectrum analyser that
would allow you to look directly at phase-nose. There are a number of
ways to determine such "quality" measurements and not all of them
require a hefty outlay in test equipment. I wonder what you are trying
to achieve with your search for a good ocxo as this may indicate what
path is best for you.
