Two rules to follow. 1 - use well shielded cables for the 10 MHz
distribution
if you wish to receive WWV 10 off the air. The skinny cables used for
Ethernet
generally don't cut it.
2. Most instruments have a high impedance 10 MHz input. Put them in
the middle
with T connectors

I don't think this is an issue, but thought it best to ask. I am
repairing an 18GHz counter and it has a 10MHz external reference port.
So does my elderly Marconi 2019A sig gen. Is there any potential issue
having them both referenced off my Thunderbolt GPS referenced
generator and counter on same
external reference?

at the same time
Good heavens, no. By doing so, they both have the same reference
and the measuremets actually means something. I have a stack of HP
stuff (3586, 3386 and assorted counters) all T'd off my Tbolt
without issue. The only caveat is that you don't put too much stuff
across the T-bolt output so
chain.

Kind of funny you bring that up. I have an old Fluke 1900A counter (plastic
case) that radiates 10mhz clock that deafens my receiver. It only took me a
week to find the intermittent source of interference Boy, did I feel
stupid...
