Thanks for the quick response. As usual, I'm learning a lot from you.
I understand that AGC could be a big problem, but I think there are ways of turning it off (depending on the HW and OS). But I hadn't given much thought to the issue of horizontal bandwidth, and I didn't realize that old analog scopes have a ton of it. Thanks for pointing that out.
I also stumbled across a very helpful article here:
