[time-nuts] GPSDO uncertainties

[donald collie]

I have a GPSDO which has a Trimble receiver, and Trimble OCXO inside.[I
think it runs Lady Heather] What I would like to know is what uncertainty
the 10MHz output will be with a 10 second count.This presumes that the
GPSDO is receiving satellite signals, and the OCXO is being suitably
diciplined. Should I expect 1 part in 10E12?, 1 part in 10E10?. This device
gives superior performance to an OCXO barefoot - but how much better? Would
somebody in the group who knows the answer, please wax elequently.
Thankyou,.Donald

The 58503A needs a null-modem pinout serial cable to connect to a PC. The baud 
rate defaults to 9600:8:N:1
