Hi Magnus, all depends - in an aircraft you have 6g+ turn-overs :) We make a version of our FireFly-II GPSDO with ultra-low-g sensitivity and ruggedization, that one you can run in a back-pack while doing skating-tricks on a ramp and you won't see much change in frequency. A bit more pricey on that OCXO of course. Most "standard" oscillators will have about 1-2ppb change after a turn-over. I have seen some that actually change the Crystal temperature when turned over, so you can see the initial frequency change due to gravity, then you see the operating current change, and the frequency slowly drift away as the temperature of the crystal is changed. Bad. Very bad. bye, Said In a message dated 1/8/2009 09:29:41 Pacific Standard Time, bro...@pacific.net writes:
