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.
