Please join us in the forum to discuss a digital sampling oscilloscope add-on for the open source logic analyzer (currently referred to as project SUMP PUMP). Our general goal is to design an inexpensive expansion board that samples analog voltages at 50MHz+.

The combination of a logic analyzer and sampling oscilloscope is a powerful debugging tool. The logic analyzer displays changes in signal states, the oscilloscope reveals how clean the transitions are.

We’re in the process of choosing a parallel ADC chip and discussing analog front-end designs. Feel free to make requests, suggestions, or just follow along.
