Made some progress tonight. I bypassed the attenuator and ran the -10dB Cal source directly into where the output of the attenuator connects (sorry, I don't remember what that's called). We're getting a signal on the scope now, which is some progress! Here's a video showing how it's going. I'm curious why I have so many harmonics of the signal...it almost seems like something a square wave would have. And the ~80MHz signal that is ALWAYS there is intriguing.?
