Picked this up for $18 at an antique mall, it's practically new. How the heck do I use it? I have the manual, but it's cryptic. I messed with it on my VT-71, but got funky looking waveforms. The tops are flat instead of humped, and I can't figure out how to get the marker to work, or if it is doing what it's supposed to, what am I looking for on the scope? A blip or something?
