I think single shot is only 9 digits. Press "mean" on the left side to get a 100 sample average that gives you more digits. On Oct 31, 2017 1:01 PM, "Richard Mogford" wrote: > I have an HP 5335A and I am measuring the output of a Suzler 2.5. I have > a GPSDO 10 MHz input

I was about to ask a related question of the list: when do you need a distribution amplifier, and when is it sufficient to just have a single (linear) run of coax? I have a GPSDO (Nick Sayer's device) that I want to use to feed a few other pieces of equipment in my lab (an HP5335A, John
