Hi all,

I just bought a EICO 330 Signal Generator and will use it to isolate defects in specific stages. It has a coax output cable with alligator clips.

Everything I read, including the EICO manual, stresses that I put a .01 mf cap in the negative lead and a 200 pf cap in series in the hot lead. I don't understand. I can solder a cap on the ground and clip onto it, but how do I put the cap in series in the hot lead and use it to probe?
