Re: signal leads that pick up less ambient noise?

Hi, I have a very noisy workbench (lots of digital computers and
computer monitors nearby) and it seems like I pick up a lot of noise on
the long leads coming out of the signal generator BNC output — around
600 mV p-p. I am wondering if there are any particular leads I could buy
that would somehow pick up less ambient noise.

I assume that your "leads" are a coax.

How are you measuring that noise? It's more likely to be ground loop
noise than coax shield leakage.

Common-mode chokes, ferrites or toroids, can help. Just plugging the
generator and the scope into the same outlet may help.
