[time-nuts] How can one measure ADEV of a good oscillator?

Just because it's a maser does not mean it has good ADEV. Masers use the hydrogen physics package to discipline an external oscillator just like a GPSDO uses GPS. So a maser can be considered to be a HDXO... hydrogen disciplined crystal oscillator. Your maser ADEV is only as good as its output oscillator/pll. Granted, if somebody is going to design a zillion dollar maser, they are probably going to use a decent output oscillator/pll.
