Super cool. Anyone recommends an oscilloscope for this day and age? I loved the Tektronix ones, but haven’t touched one in 16 years. I think it would be nice to have one to look into these kinds of signals - I know they are relatively simple enough to imagine, but this looks like something cool to show to kids.
The USB and handheld ones are great and can be had for less than $100. The Hanteks can be interfaced with open source software which is great since you get a ton of features that normally wouldn't be included in budget models (like wire protocol decoding). As for benchtop models, Siglent and Rigol are going to be the most affordable. There's a way to generate license keys from certain models if you care. Obviously Tektronix and Keysight are top end but are like 10x the price of Siglent/Rigol.
