I was directed to this group when I asked this question of another group.

However, after reading some of the emails I am a real novice when it comes

to this stuff. I worked with cesium and rubidium oscillators as Primary

Reference clocks in the telecommunication industry. When I was there I

wrote a basic program to retrieve phase offset between two signals over GPIB

from a counter. The program then calculated frequency accuracy and did some

Allan Variance calculations. I am trying to replicate that with an Arduino

and a simple phase comparator. I have forgotten the math and I am not smart

enough to glean it out of the data presented on the internet. Can someone

point me to some example programs that will allow me to measure phase offset

over time and calculate frequency accuracy and do some basic Allan Variance

calculation.

Thanks,

Daniel H. Pressler, KF2HP
