Accurate enough so that if its reading matches the posted sign, you
don't receive a ticket?

And faster speedometers make your warranty run out faster, which nobody
except the car companies like.

OK thanks, I couldn't find the link for the thunderbolt. The Agilent manual
states the best it's LO is 1 X E-10, (I think). I was just thinking
expensive test equipment that was recently calibrated versus junk GPSDO that I
salvaged from telco equipment.

versus junk GPSDO
It's not junk.
What are you interested in? Short term stability or long term accuracy?
I'd expect the GPSDO to be more accurate over the long term, but probably
wobble around slightly at a time scale of a few seconds as the D tries to
keep things on target. An equivalent

I'm glad to hear that the Thunderbolt is not classed as 'junk'... :-)

A statement of accuracy is of little value unless you also give:
1) An estimate of the accuracy of standard used for comparison.
2) An estimate of the random and systematic errors in the comparison
3) Some details of the comparison method.
4) Averaging time and other pertinent info.

No. Details like that does not comes into play. If the quality of the
gear does not match the specs, the manufacturer gets a serious problems
so

The judge told me I could use this only once.
