[time-nuts] Best counter setting for ADEV?

[Azelio Boriani]

Taking 10 samples from a 1nS counter leads you to a 100pS resolution but
the noise at best (if it is really random) is reduced by SQRT(10). So, as
already pointed out here, there is no real substitute for lower noise,
higher resolution measurements.
