I found a BNC to female RCA adapter. It plugs right into the the

and 1/4" on 
> the other to patch into the modular. The adapter was only two or
three dollars. 


There's the spirit!  Adapters are perfect, letting you use the most
often required cable connector and still allowing for everything else
in your lab to have a place in your system.  Your DMM uses banana
jacks, your oscilloscope needs BNC, your Blacet and PAiA gear want
1/8" jacks and if you have adapters, you have connections to all.

Plug in, tune in, and ignore the yard.
