In summary, to measure the accuracy or stability of any clock, you always
need... a better clock. Or you can use the "three cornered hat" method, but
it requires that the accuracy or stability of the three devices under test
**should not be correlated**.

Hi
If you are trying to evaluate things like accuracy and stability,
you really can’t do it internally. You need something else to
compare to. If you want to count number of dac bits of change
per hour, you certainly can measure that. Just what it means ….
