[time-nuts] Measuring Phase diference between different GPSDO

According to http://www.realhamradio.com/z3801a-turning-point.htm they use a HP 3575A phase meter to perform the measurement.
Or perhaps I have misinterpreted the whole thing?

I do have a temperature controlled workshop that is always 24 degrees so hopefully thermal drift won't be too much of an issue.

Meditating on this a bit, I assume in a strict sense, you can only consider GPSDOs phase locked if they are disciplined from the same GPS.

Or is this being pedantic?
