I have a Siglent SDS1104X-E scope, it's a step up from the typical Rigol DS1* in my opinion in both use and features. I've also had the Rigol DS2x and Keysight DS3x series at work, and various Picoscope PC scopes. Stuff I find better with benchtops: - display update rates (I've caught random glitches I would never have been on a PC scope) - sample buffers - display options (persistent, colouring etc) - segmented capture modes (Siglent call it "history) - protocol triggering, which is incredibly useful for working with UART/CAN/SPI etc. Keysight nailed this. - glitch triggering - just triggering in general - realtime online protocol decode - user interface (in terms of having knobs and buttons rather than clicking on stuff) Basically, I use my scope a lot as a more powerful logic analyzer for signals using less than 4 channels. I do have a backup LA, and Sigrok/Pulseview are fantastic when required (and support a lot more protocols). But a logic analyzer is never going to show you if you've got signal integrity issues. As to why there aren't any open source benchtop scopes, good point. At least my Siglent is Zynq based with Linux for the UI/rendering/networking and FPGA for the quicker bits. The Keysight's have custom ASICs. Bunny's Novena could be a good start towards the hardware.
