Main goal is to use it to compare waveforms from the SM to actual in the horizontal blanking and convergence circuits. The SM mentions 7875 and a squiggle after it and the manual for the scope says that horizontal should have a cps sweep of 7875. Is that what you mean by bandwidth? If so, it seems that all the circuits I need to test are either 30(squiggle) or 7875(squiggle). If you know what the squiggle is actually called, please tell me. I'll feel so much better being able use the proper terms.
Also, in one of the pics I attached there's a probe in the bottom right. It came with that and standard leads like a DMM. Is the probe needed for checking the horizontal pulses and the convergence board waveforms?
I've never used one before, so I'm pretty much flying by the seat of my pants.
