I have bought a cheap Hantek 6022 which has a logic analyser and Oscope.
Its official software is outdated and useless. Luckily, there are open source software suite and drivers for it. Finally, I can run my Hantek on PulseView and Openhantek.
How do you rate PulseView v0.5.0 as a logic analyser? Its GUI is great and support, hundred of protocols, I think. Here shows a small part of its supported protocols.
