Product Description
This pocket-sized two-channel oscilloscope allows for observation of varying signal voltages and currents. Great for hobbyists and tinkerers, it comes with a full-color capacitive touch display with 320 x 240p resolution for easy navigation Read More
There are newer version of this oscilloscope: DSO DS213.
I watched fiew reviews of DS203 and maximum analog bandwidth is limited to sinusoidal signals, for square shaped signals safe approximated maximum bandwidth is about half of declared 8MHz and even for slower signals readings will be significantly distorted.
My bad. DS203 has 8MHz bandwidth, DS202 has only 1MHz. So... I suppose real and usefull bandwidth will be even more smaller, something about 200-400kHz...
Jackv4546Depends on your needs really. It doesn't have a huge bandwidth but it's portable. At this price range I'd advise getting oldschool used one with CRT screen. So in the end it boils down whether you want portable and new or more powerful and heavy used one. I advise taking a look at EEVblog's video about getting used scopes: https://www.youtube.com/watch?v=rTPhuRQBmLQ
I mean it's pretty cool as a cheap gadget. But 1Mhz B/W? For $80? What's the point... you could put that towards a real oscilloscope !

ronmacdonIt fills a specific role of portable oscilloscope. Personally I'd suggest getting an oldschool CRT scope for that price if someone just needs a scope. Finding a portable one at this price-point is damn near impossible.
