That seems good enough.
Some generators put out other patterns that are more useful when looking at the signals with a scope.
If you can, try the generator with another working TV, some flat screens can receive the analog channels. I don't know if the kinks at the intersections are due to the generator or that TV. Flat screen sets do not have this type of distortion.
