Granted I expect someone on this list to reply with something that makes me
feel stupid, if you have two GPSDO units running side by side, should the phase
delta on the 10Mhz output be zero (ideally)? Is there an absolute phase
standard kept between GPSDO units as all it would take is one extra inverter in
the chain to flip the phase, no?
I don't think so..
GPSDOs are really more of a syntonization (same frequency) rather than a
synchronization (same phase) box.
You might have two boxes of the same kind that have some well defined
and stable phase relationship between, say, the 10 MHz sine and the 1pps
(if the 1pps is derived by dividing the 10 MHz, for instance)
