Hello Ulrich, This is so true. See Tom's phase noise tests of a Russian Rubidium prototype disciplined by a Fury GPSDO. Lot's of times there is not much space to put a good OCXO inside the Rb's case. BTW: using the Fury's 1PPS input, that unit can be used as a cleanup loop for dirty Rb's that have 1PPS outputs. _http://www.leapsecond.com/pages/fury/phase.htm_ (http://www.leapsecond.com/pages/fury/phase.htm) I just fired up my FTS1200-100 tonight for testing, it's dead on 5MHz. Does anyone have a good circuit idea to go from 5MHz to 10MHz? I was thinking of something similar to the HP5370B input circuit - basically a tuned amplifier locking onto the 10MHz overtone. bye, Said In a message dated 4/19/2008 06:33:21 Pacific Daylight Time, [EMAIL PROTECTED] writes:
temperature related frequency changes in a typical flat. Given the fact that most rbs's stability at short observation times is worse that that of good xtal oscillators this makes the FTS1200 the best choice in my GPSDO despite of owning an LPRO101 and an FRK-L.
