[time-nuts] Allan Deviation

[Martyn Smith]

Hi,

Thanks for the answers but I'm still confused.

The Stanford PRS10 has an Allan Variance of 2E-11 but a Symmetricomm unit 
has a Allan Deviation of 3E-11.

So according to the answers you gave, the Symmetricomm unit has a stability 
thousands of times better than the PRS10.

This, dispite the Symmetricon unit having 25 to 40 dB worse phase phase 
noise than the PRS10 (at 1 and 10 Hz offsets).

Surely that's not possible since the PRS10 is pretty good in the first 
place.
