Tom,
The ADEVs I quoted are from the Z83xx software, so I assume it's
comparing time from the GPS system to it's own oscillator's output, in
the same way that LH does. I've been monitoring the basic stuff you
suggested.
It's because I don't have a known reference to compare the units with
that I want to use the 3-corner method to start sorting the wheat from
the chaff.

I have an HP 58503A and a Symmetricom 58503B which are behaving quite
differently to one another using a common antenna. Using Z38xx, there's
almost an order of magnitude difference between the reported ADEVs at
40k seconds (HP:7e-13, Sym:5e-12). Both have 10811 oscillators and are
Where are you getting the "reported ADEVs"? What counter, what reference, what
software?
Did you happen to periodically log any SCPI data during the runs, so that you
can compare SV counts, signal strengths, TI averages, and so on? In general it
might be good to have a quick look at this mundane data first.
