ADEV is about characterizing noise powers. The better variants such as
TOTADEV and TheoADEV will be even more efficient at
The trouble with ADEV is that if you average
a long time it papers over anomalous events
like crystal jumps. An alternative measure
might be to, instead of averaging, simply
keep track of the worse case change in frequency
during 1 sample period. Sort of like peak jitter
versus rms jitter.

if the noise isn't nice? Are there alternatives? What's the mathematical

I can think of 3
Tou can try some chaos analysis on the phase space (not the phase of the
signal). It may be that some kinds of shifts are chaotic.
