I am envisioning s.th. like 10^-15 for Rb/Cs oscillators (=minute
timescale) - but I guess it should be not too hard for a Dual Mixer Time
Difference system. Not a clue, how much the 5125A from symmetricom might
be... but in principle, this is a bunch of minicircuit parts, isn't it?

It would be great if s.o. has a circuitry!

Cheers
