I'll worry about that if I discover I have to do an RF alignment later. Right now all I want to do is an IF alignment.

EDIT: Nevermind, I re-read that and I think I misunderstood you. But yeah, I'll keep that in mind.

EDIT 2: Yeah, definitely misunderstood. It's going to output some frequency regardless of if it's RF, IF, whatever, and you're essentially saying I can't control the peak-to-peak voltage with this. Since my TV is looking for a sweep with a 3V peak-to-peak signal, hooking up a potentiometer on the line to control the output level would be useful.
