You can find the book on-line, look for "Dual Voltage Global ositioning System Timing Module (GPSTM) OEM General Specification". Yes the ower supply is speced from 24 to 48VDC plus or minus. They don't specify AC, ut since the bridge is there it will work. 2.08A warm up and .6A@36VDC steady tate. I'd like to see some of your LH traces if you don't mind, especially the osc race. I don't seem to be able to get my osc trace less than ~400 ppt/div. You an see pics of my unit and traces from LH here http://s251.photobucket.com/user/DogTi/library/time?sort=3&page=1 Dave ______________________________________________ ime-nuts mailing list -- time-nuts@febo.com o unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts nd follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
