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 for part to the
-nth
In the 10-9th position on the selector switch the a given oscillator will
show a 0 to 360 degrees travel lets say in 1 second.
So does that mean that the DUT is off frequency compared to the GPS input by
1 cycle in 1 billon?
What if it takes 10 seconds to make the 0-360 excursion?
100 seconds?
