Back to the VT-71H

Keeping in mind, I just got this thing and my skills with it are very, VERY limited, I took pictures of the waveforms of the signals going into the video amp pin1, and out the video amp pin 5. The scope has an auto trigger and an auto adjustment feature that creates the best display parameters. First in pin 1 input from the detector. The second is pin 5 video output. Am I doing this trace correct so far? I've never looked at a video signal on an oscilloscope before. I'm feeding an RF modulated video into it and I have sound but no image information on the CRT...just a raster.
