[time-nuts] TDEV or phase Dev for a GPSDO?

Has someone already done the work and plotted TDEV or phase Dev for a 
run of the mill GPSDO.
Particularly for a GPSDO with a non-exotic oscillator.. Or, perhaps the 
USRP flavor?

There's a fair number of Modified ADEV plots out there from time-nuts 
and others, so I can calculate it, but hey, if someone has done the work 
for me, I'm lazy.

http://www.leapsecond.com/museum/manyadev.gif for instance, tells me 
that at 1000 seconds, a  TCXO has MDEV of around 1E-9, so TDEV of about 
0.6 microseconds, and a Z3801 (MDEV 0.5E-11) has a TDEV of 3ns.
