At what point does one require a distribution amp? My TBolt currently
provides a reference clock for 2 instruments, and I know of no issues.
Since the unit came with the 1:2 Mini-Circuits splitter, I expected this to
be the case. If I switched to a
ZFSC-4-1<http://www.minicircuits.com/pdfs/ZFSC-4-1+.pdf>1:4 splitter
say, to add a reference to a 3rd instrument, at what point
does this become an issue if the insertion loss is only -6dB on any port?
HP provides both the input impedance and the capacitive load for a 5334
counter, which is nice, but this does not seem to be a standard or norm per
se in the T&M industry.
OTOH, I don't want to over think this though :-)

I have a FlexRadio 1500, Racal 1992 counter, HP 3586,
Advantest U3641, and Gigatronics 6061A daisy-chained
off my Thunderbolt. Don't throw out those BNC T connectors.
The Gigatronics terminates the 10 MHz so a splitter or
something may be required if I add another instrument
that terminated the 10 MHz input.
You need to use lab grade cables if you don't wish to
interfere with WWV on 10 MHz.,
