  • [Wiki]DSO Nano v3

    DSO Nano v3 is a portable digital storage oscilloscope. Based on a 32-bit ARM Cortex-M3 microcontroller, it is equipped with 320*240 color display


Great little hobbyist Oscilloscope The DSO Nano V3 is a very handy little oscilloscope for those who require basic functionality at a reasonable price. While it won’t substitute for a full bench scope it is handy for quick readings and insight. I purchased mine to help determine wave shapes coming out of my modular synthesizer and for my purposes it works great. While it might not be for everyone it does the job in a pinch. The quality of the unit is very good and it holds up well to being shuffled about amidst all my gear. While the documentation is not outstanding it is quite adequate. Finally, dealing with Seeed Studio was a pleasure. I got exactly what I ordered very quickly. Thanks folks!

Really great. Full metal body, good accessory: metal table stand, two probes, cover. Quality of body material and assembly such as Apple iPhone 4 or 5 models – it’s really great.

This is a really good scope for the price. It took me a little while to figure it out because the manual isn’t all that useful (it does give hints though). It has a ton of features and, once you figure out how to use them, it packs a lot into a littl
