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.
 

One thing to notice that RG58/BNC cables are not created equal. There is big differences in transfer impedance (shield effectiveness). Some Chines cables are good, others are crap.
A good coax cable is quite expensive.
When doings measurements on either conducted immunity or using near field probes, it get even more evident that the cable quality has a large effect.
