I have a decent PC o-scope; nothing special (Visual Analyser). I am wondering if I can use this software to poke around in amplifiers....some may have some pretty high voltages present!!
So the question is, is there a resonable way to be sure an input (via soundcard line in) will stay below a certain voltage (lets say 5V to be sure!)? I guess what I'm looking for is to scale the higher AC voltages (assume 200V) down to 5V, with a protective device in place to assure not blowing up the sound card (zener....).
Just an idea, and maybe a dumb one at that....thanks for any ideas!
