I've been working on a number of electronics projects lately, and while I have a 'scope, it's fairly poor to use (it's one of those pocket ones, and I have complaints about its usability).

Do you know of any PC-connected oscilloscopes that use open-source software? There's the Analog Discovery 2, and the OpenScopeMZ, but those both use either Waveforms (which is closed-source, though free) or Waveforms Online (or whatever) which is allegedly open-source, but that doesn't count since it can't be completely run locally (as far as I know).

WFO supposedly can run offline, but that's only the case as long as I don't close my browser or reboot for a kernel update. If it can be downloaded as a standalong webpage to run offline, that's a different story.

Anyway, please let me know what systems are both good quality and have an application that works offline and is open-source. Thanks!

I've moved the question over here from regular SE since I've been told it fits better. I still don't have access to tags that fit the question better, though.

Have a look at the list of scopes supported by libsigrok - it is a fully open-source, GPL licensed library for working with various kinds of EE measurement tools.

Outside of that PicoScope has - as far as internet says - a great SDK but it's closed source.

  • That seems helpful. Does sigrok provide a UI for using the tools, though, or is it an interface library where I'd need another program? Their docs page doesn't have a section for using a 'scope (or say whether it contains the interface), and googling it didn't seem to recognize the name.

  • Although from my experience most of their GUIs are not that good. Their wiki lists some more, try googling for "sigrok oscilloscope GUI"

  • Ah, I see what you mean. That might work, but I have to admit that I'd probably prefer something with a more polished-looking UI if I purchase something. I'll admit this might be hypocritical if it works well despite its appearance, but that is still something that matters when using a program.

  • @RDragonrydr there are very few OpenSource programs with a polished, modern GUI in general. My knee-jerk reaction is to tell you to buy commercial or improve it yourself. Why do you need it to be OSS anyways?

You can take a look at Saleae:

Their equipment is relatively expensive, but very good.

(I'm not affiliated with them in any way, to be clear.)

    Do they have source for their software and/or device firmware? All I saw on the github page was for creating plugins for their application, but not for the application itself.
