  • I’ve got a Rigol DS-1054 and the serial decoding is terrible. It can capture 24 million sample points, but it will only decode from the few hundred points that are displayed on the screen. That means it will only decode a few bytes of data. I don’t know if any of their newer models have gotten any better.

    Definitely get a 4 channel scope. The extra channels will come in handy even if you think you don’t need them. The digital channels tend to be less useful. The 16 channels you get on a scope are not enough to probe a parallel bus, but way more than you need for serial. I would rather use a USB logic analyzer. It’s easier to work on a PC with a big monitor and the ability to write your own protocol decoders if needed.
