      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!

      DSO NANO V3 The user manual is not totally updated. The procedure for saving data is not correct.
      Could you please update it and send me the new version?
