Are these things I should consider bad

Depending on the scope I was using I almost never used
DC only AC since I was looking at waveforms. On my sencore
there was a built in meter to speed things up.
Also be sure all your calibrations are set. The are the red
knobs are set to "cal". Some have an arrow to show which direction
to turn them.
If the scope is dual trace you can use sync on B to stablize the
waveform. Hook the B channel probe to a clean hoz signal
such as the hoz drive collector, this may get rid of the multiple
traces.

I'm using the horizontal trigger of the pattern generator. Is that basically the same as using the B channel on a clean horizontal signal?

Yes, the red knobs are in the calibrated position. Not ready to mess with those kinds of adjustments.

When I check the C1, I get a staircase type pattern. Is that what it's supposed to look like? I have the pattern generator on the color bars w/IQW and chroma off. That gives me long b&w bars on the screen.

Inside the set there's a sheet glued to the wall. It has a section w/the heading of "Major Test Points". The first one is C1 (Picture Detector Output). The other two are used for calibrating the ACC and some IFAGC.
