Product Description
The Seeed DSO Nano V3 is a pocket-size 32bit digital storage oscilloscope that allows observation of varying signal voltages, and currents. Great for hobbyists and tinkerers, this oscilloscope comes with a 320-by-240-pixel display, USB charging port, and six easy-to-navigate buttons to change functions and measurement Read More
Where do I get warranty support for this unit? I got this from the last run i believe and it's been sitting in the box ever since. turned on when i first got it, won't turn on now, even after overnight charging. it does show up on the computer as a disk drive however. compltely blank/black screen
I have a version 2 one of these I got on eBay a while back. In my experience these devices are kinda a waste of money as they start aliasing on any signal past 1 MHz, and they are impossible to trigger any waveform on. They are kinda neat in the sense they are based around a micro-controller, but they don't seem very practical.
EEVBlog did a teardown/review of one similar to this (they all seem to be based around similar design) on YouTube.
Now if Massdrop could do a groupbuy for a more serious scope - I'd seriously consider it :).
Unless you REALLY need the portability, save your money:
- Its really annoying to to use (like navigating windows with the buttons on a digital watch)
- Poor performance in all measures except physical size
- Better benchtop scopes are available on ebay for <$250 at any point you want one
- I owned one of these for 3 years and have started driving to a makerspace when I need a scope instead of bothering with this.
I would like to measure jitter on my computer's USB port (feeding a DAC at USB 2.0 speed).
Is this oscilloscope capable? Is it accurate and sensitive enough?
I need a miniature 'scope that can directly display XY -- that is, a LIssajous pattern. Thsi requires a direct X input, replacing the timebase. This unit doesn't appear to have it. Am I missing something?
Thanks.
OK tech guys... I'm gonna just let my ignorance hang out here, so don't be too hard on me. Can this be used as a real time audio spectrum analyzer? Meaning, I'd like to identify spikes in specific frequencies so that I can stomp out feedback for live performances.... i.e. ooh! that ring is at 90hz, let's turn down the 90hz on the EQ and get it to stop. I currently do this with my cell phone and it's microphone, but something wired and sitting on my mixer would be nice.
MikeUnderhillYou're looking for something that can do an FFT (Fast Fourier Transform). Looking at the specs, it doesn't look like this version can (from what I can see)
