The "height" ie signal amplitude and wave shape of composite video and h osc waveforms are going to be radically different... the goal is to compare the synch frequency (width between pulses) and h osc frequency to allow calibration of osc frequency to a known reference.

So something ive been meaning to ask as Im having difficulty finding the answer in the sams. What would be the "normal" operating condition position for all the switchs? I had the yoke pulled back before it went on the bench and the red/blue/ green looked great as is with minimal smearing. I had a red blob centered. I know the norm/service/raster switch should be in normal but what about the color guns and all these other controls? Where should they be so i can get something on the screen?
