Been doing some digging now knowing about logic analyzers and I found that RIGOL has some oscilloscopes with digital channels that are within my budget range (needs the RPL1116 probe to function). Though they're bandwidth is 100MHz for the one's I could find that are under 500-1,000$. Would this be enough at least for USB 2.0?
Does it have built-in USB decoding? If not then it’s not very practical tbh, but it could do low speed and full speed, with manual decoding. Not high speed.
OpenVizsla can do high speed: https://shop.sysmocom.de/USB-Tracing/
What are you after though? A scope is more fun. :)
I'm trying to learn electrical circuit design and programming and want/need an oscilloscope for obvious reasons (I already have most of the basic stuff such as a soldering station and a multimeter). I know I want to work with various ICs, FPGAs, and of course stuff like USB to plug stuff. Though budget isn't that extravagant, I should have decent wiggle room (I suppose totals of below or around 700$ is fairly manageable at the moment).
