Hello to All, I understand (e.g. from Mills papers) that the Allan variance can be used to characterise timing sources and clock drifts.
I was wondering about the significance of calculating the Allan variance for a clock disciplined by NTP, while being affected by network jitter (assuming high quality timing source). Can the Allan variance be used to provide a quality measure of NTP in a particular network? or lower order statistics, such as mean of the frequency/offset errors are more apt to quantify NTP. My aim is to provide a quantitative measure of NTP ability at disciplining a particular oscillator, under different network jitter. Such that a minimum network quality can be recommended in order to achieve given accuracy (or in my case frequency stability). Anybody has done any work in this direction?
