The question can't be answered without knowing what the range switch does. In my experience, the cycle that is divided into 360 degrees is the period of the input signal regardless of the range switch. You don't say, but the usual GPSDO produces a 10 MHz signal, unless it's for a telco

Hello, I know this is really a basic question. I have a Fluke montronics frequency comparator. It has 2 inputs, one from my GPS and one from my DUT. After a given oscillator is warmed up, I can read the meter in parts 10 -X There are 2 meters, One for phase 0 to 360 degrees, and one

Hi Not having one here, about all I can guess is that there are 360 degrees in a cycle. If it’s going through 360 degrees in 10 seconds it’s 0.1 Hz off at what ever point it’s comparing. If it takes 100 seconds that’s 0.01 Hz. Yes I get this pesky decimal point stuff wrong from time to time
