I had an old USB Oscilloscope (StingRay), it's 20+ years old now.

Bought a OWON HDS242 with the hope that I could view some stuff on it's screen, but still hook it up via USB to the computer and do some voltage data logging. It doesn't seem to work like I would like it to.

So I've learned what I want is a Data Logger and not an Oscilloscope.

Can anyone recommend a good USB Data Logger that won't break the bank?

Decent bit ADC, and something that can get down to the 1us.

Doesn't need to be high voltage.

Cheers,

The Original Saleae logic analyzer (or one of its clones -> search for "Compatible Saleae") or a LA104 (maybe with custom firmware) or maybe a DSlogic pro or ChronoVu. You can also browse the HackADay Archive to find an analyzer that suits your needs (e.g. build your own, or based on a pico). It all depends on the resolution/speed you need and usecase.

USB isolator, $10 saleae clone and sigrok/pulseview setup is very simple and cheap (except for the isolator).

Thanks for the info!

What do you actually need? 1 microsecond with "decent bit" is not exactly a lot of information. An oscilloscope would fit that perfectly. How do they not work how you want them to? Who told you that you need something else?
