Purity you can do without a pattern generator.. Lower both green and blue drives on a station that is not coming in (Just Fuzz), and then once you have the yoke adjusted, you'll have to switch to a TV program to level all three drives.. If you can find a station that is letter box, you can go by the color of the bars on the top/bottom to level the grey scale.. I think there is a place to where you can download a DVD of the patterns... Convergence you'll need the patterns and using the cross hatch pattern is the best for that, or at least for me it is..
