Analog Discovery 3: 125 MS/s USB Oscilloscope, Waveform Generator, Logic Analyzer, and Variable Power Supply

Best of the market

It’s built well. For a hobbyist, trying to understand how electronics work on a deeper level, this is an invaluable tool. And the WaveForms software suite that pairs with it is just excellent too, once you get to know it. (You can even download it now and play with their sample software emulated scope to get a feel for whether you’ll like this hardware and if it’ll meet your needs)

Only used it as an oscilloscope so far, I’m sure it has tons of features that I haven’t figured out yet but my only gripe is that the waveforms software used with it is a bit clunky and difficult to navigate. I was getting frustrated trying to figure out how to enable trigger mode, and zooming and panning are way more difficult than they need to be. However, I can already tell that this is going to be an indispensable tool in my electronics kit. Edit: trigger mode sometimes misses when voltage goes above threshold
