I recently got a DSO-2090USB, but when taking measurements, the zero reference line always seems to stay at the bottom of the screen, no matter where i put the channel's zero reference point.
Maybe i'm doing something wrong, because it also happens in the official windows software.

Anyone got a clue on what the problem might be?

Thanks to fabio for his excellent article and response on his blog, I reflowed U20 (DAC) and its surrounding components, and the 2090 is working as it should again
