[time-nuts] A counter for phase measures

Dear fellows,
I'm searching for a counter that allows me to make automated measure
series. Of course, Allan Deviation is an important thing to determine
when experimenting with or developing GPSDOs (what I intend). So it
seemed to be a nice thing to measure phase deviation with a counter (HP
53132A or SR-620 or so).
When experimenting with that stuff I discovered, that all my equipment
would not be adequate to determine Allan Deviations beyond 10e-11 (or
so). The question is, can any counter deliver that precision / low noise
to make such measurements possible? Or does it have to be a more
sophisticated technique, such as cross spectrum analysis?
Thanks a lot in advance
Volker
