Here's a link to firmware version 00.04.00.00.01 for the DS1000D and E series:
http://db.tt/tX3qsxYTI got it after asking our dealer if there where any upgrades. Its pretty annoying that rigol doesnt put these updates on their site i think.
Also notice how the major version changed again, from 3 to 4 this time. I wonder what they changed. The included .doc file only mentions a few minor changes which dont jusitify changing the major number it think.
Note: I didnt try this update yet. Im still waiting to see if someone will figure out a easy and safe way to upgrade my DS1052D to a DS1151D.
The only reason to upgrade would be to fix a issue with the long memory: It only seems to work if you capture stuff in single shot mode? Why is that? If i just stop the scope manually, i cant zoom in on the signal nearly as much. Is this a bug or feature? The manual and helpfunctions aren't very clear about it either.
