Hi! I bought a Trimble/Nortel GPSDO
http://www.ebay.de/itm/300933951405?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2648 and Lady Heather's now tells me that everything is alright - except - DAC 6.000004V - OSC BAD - osc age alarm The rectangle "10MHz" output signal (J5) shows a signal at about 9.8MHz (a deviation of about 200kHz), wobbling 4Hz up and down. Oddly enough, the direct oscillator output (J4) shows a sine wave at a stable 10.0000004MHz (a deviation of 0.4Hz). It seems to me it's not the oscillator that is bad but the servo loop - what can I do?
