DSO Nano Oscilloscope v3 Review
DSO Nano v3 is a 32bit digital storage oscilloscope. Based on ARM -M3, it's equipped with 320*240 color display, SD card, USB port and recharging function. It's compact, simple to operate; meets the basic demands of school lab, electric furniture repairmen and electric engineering. The version 3 of DSO Nano differs from version 2 in that it does not use white plastic shell. Instead, it uses black metal shell which is more durable and strong.

Quite Good for What It Claims to Be...
By Let's Compare Options
This scope is identical to the V2 in "guts" and features, but has a metal case at about the same price as the 2. If you want all the dope on function and features, see the 20+ reviews on the 2 here: DSO Nano oscilloscope V2. There's a well done pdf users manual online too-- same for this and the v2.
Points not made in previous reviews:
1. The metal case IS nice, and there were complaints about the plastic having range problems in the heat. I have both and both work great for single channel applications.
2. A GOOD two channel with all these features can cost as much as $500 on up. It would be better to get two of these, then compare oscillations -- AUC's without the overlay if you're not too picky about pinpoints and want to see general signal comparison trends, which work for 95% of checks. You're going to pay quite a penny (nearly 300 low end, 500+ higher end) for a good 2 channel unit like: Owon SDS7102 Deep Memory Digital Storage Oscilloscope 2-channel with VGA and LAN interface. The question to ask is do you really need the waveforms on top of each other, or can you just put these little units next to each other and get the same info? They're pocket sized!
3. Comparing this to my big brother lab units, measurements are within 3%, not bad for hobby applications. I use it with the raspberry pi and it works great! I've used the v2 on the Arduino forever and it's fine for nearly all checks and comparisons.
4. Other reviews have recommended you swap out the OS on some of these versions-- DO NOT do this on this unit or the 2 until you try it. It's been updated many times since those reviews, and you're likely to be happy with this out of the box. There are polarity issues for the signal generator, but an easy fix, see the fixes in the version 2 reviews mentioned above.
Gabotronics has also just come out with their xprotolab portable, at about the same price. Sparkfun will likely put it on Amazon sometime late in 2013 when it ships reliably. We did a number of regressions of quality indicators by price for ALL current digital scopes, and the best price/feature fit was by megahertz measured. The y=mx+b regression factor is .1295 with a 99% fit to data, so if you divide megahertz desired by that factor, you'll get a close estimate of what you'll have to pay. We tried to put the full regression in this listing as a picture, but Amazon doesn't always get what we're trying to do and removes it! Just put your mhz in 50 mhz increments from 50 to 1,000, divide by the regression coefficient (.1295) and you'll get a good estimate. For 50, you get about $386, which is quite accurate.
Happy measuring! This little devil takes your Multimeter to the next stage, and will impress your friends!

Sweet Mother Of Pocket Sized Oscilloscope
By Paul C. Skertich
You don't have to update the firmware but you want to then please follow the instructions that came on the website. There's a updated firmware and manual on the website and I believe a printed manual too. However, took me a bit to get a hang of this but actually it's pretty cool! It's pocket sized, rechargable and perhaps some day it may go higher than 200 khz or whatever limit they have. if you're looking for something that goes higher than this products frequency limit then find one. However, this is neat because you can carry it on the go where ever you want to test. I do wish the manual was more explanatory or there were better tutorials. However, once you get the basics down then you're good to go!

An extremely useful tool for a low price
By Steven P Donegan
Very solid metal case, works like a charm, for low frequency work it is perfect. It arrived on time and was exactly what I ordered.
