Are you talking about the PPS output or the frequency output (10 MHz by default)? I haven’t attempted to get ADEV plots of the PPS output mainly because I’m not sure the best experimental setup. I could (try to) capture time differences between the PPS output of a thunderbolt and the PPS output of the Venus, but would taking the ADEV of that give correct results? > > Lars > > >> Nick wrote: > >> Jim Miller's 10 kHz GPSDO that’s been referenced here has either solved this >> problem, or the 10 kHz output of the >Jupiter is substantially better than >> the Venus’ 10 MHz output, or the design doesn’t give the results time-nuts >> expect >from a GPSDO.
