It has a 10 MHz output, so could be made to work with the 5000a. You
might have to adjust level. My thunderbolt was approx 3 dB too hot,
so I ran it through a TV antenna splitter to drop 3 dB.
It needs a GPS antenna - maybe he has it.
Join the FMT-nuts reflector (see www.k5cm.com ) and ask for more
there - someone may be using it already.

Another question from this total newbie to frequency measurement...
A friend has offered me (as in free, come get it) a "Spectracom
NetClock/GPS 9283." Is this (1) suitable as a frequency reference
for my 5000a and (2) useful for the FMT exercises?
Also, can someone point me to any kind of beginner's guide or tutorial?
Many thanks,
Bill

Thanks for the info. I wanted to try this but lacked the motivation
to set everything up. My Thunderbolt is still in its ebay box...
This is just the poke I need to get going.
