nice unit, very compact, useless
This review is from: ARM DSO203 Nano V2/Quad Pocket Digital Oscilloscope
Pros: small unit, very well thought out, worked and provided a signal, 10 on coolness factor, 1 on usefulness factor. Liked the form, and the function, but was just too small to be useful on a daily basis.
Cons: although I got a display of the waveform, all of the functions were so small could not read them without a microscope. waveform was correct, but did not reflect the 20 volts from ground, at least from what I could get onto the screen. The 3 volt waveform was accurately displayed. Not a useful tool, screen just isn't big enough to use except to ball park
Other Thoughts: thought it was bigger, say tablet sized, that would have been awesome!!!!! maybe they'll get it. also no touch screen yet, 5 years and this will be a real deal.
