I have the same equipment and don't need insane accuracy (1Hz in 100MHz is more the sufficient - 10e-8). ?I will put the 1PPS signal into the A input, the 10MHz from the ref osc out on the back into the B input and use the B/A ratio mode and set the resolution to get the desired LSD resolution. ? It will pretty much stay on 10000000.0 for hours with an occaisional blip up or down the LSD. ?When it jitters up as often as down, I'm close enough for my hobby use. ?Better signal lock results in less jitter (outdoor antenna is better than one of those fingernail sized things indoors).
