Well, I BOUGHT the 6022 and it does NOT have an AC mode so just maybe I know something about it. This actually very common on the low end scopes. The software was set up for it, but it does not have it. There are multiple hacks on the WEB to add the feature and allow the UI do do the switching. They seem to me made for simple digital work only. So, yea, no coupling cap so it would be IMPOSSIBLE to do it on the screen as the A2D is DC coupled. Thinks about it!
In comparing it to the one I now have, I would say the 6022 had more than one bit of amplitude jitter. I would love to have the budget for the $400 version with 12 bits and even higher sensitivity. I may built a high gain front end so I can do things like look at noise on various sections of a board.
