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.,
