Dangerous DSO is a new logic analyzer/oscilloscope prototype we've been using in the lab. It combines a 16 channel logic analyzer with one 50MHz oscilloscope channel with +/-10volt DC range. The combined tool shows what your signal does between 0 and 1, which helps pinpoint noise and other electrical glitches.

Our goal with the D-DSO is to make the simplest possible oscilloscope reference design. It doesn't have range selection or AC coupling, it's a basic design that shows the bare minimum needed to capture an analog signal.
