200mV input of 21.25mc signal. This is swept symmetrically through 1.0mc as the alignment instructions say. The shape of the right side of the curve curve doesn't look like Fig. 13 in the service data but it is sorta symmetrical and the 3 markers are where they are supposed to be I think. The trace should begin ascending back up after the third marker (21.43mc) but it isn't and I don't know if that's important or not. I have the scope probe grounded through a 1000pF capacitor. The fuzzy smearing doesn't appear to be an issue anymore. In person, the line is tighter than it appears in the photo.
