You might want to have a look the discussion Subject: is there a cheap and simple way to measure OCXOs? Date: Wed, 30 May 2012 15:11:03 +0200 Where i asked how to measure the phase noise of (coincidentaly) some 8663's. One technique to measure the phase noise would be to use your PC's sound card (or rather a low noise external sound card). You can find details how to do that at http://attila.kinali.ch/phase_noise_measurement/ (Again, thanks to Azelio Boriani for the translation) There have been many discussions on phase noise on this mailinglist, you should be able to find plenty of input how to improve your setup in the archvies.
