PicoScope 2204 USB Oscilloscope Review

PicoScope 2204 USB scope

One of the nicest things when starting a new hobby is that there’s just so many things you don’t yet have, and can thus look forward to researching and then maybe buying if the price is right. In electronics, you can pretty much get started with a $10 soldering iron, $25 multimeter, maybe a $30 programmer if you want to use microcontrollers, and then just buy cheap components to tinker with. But sooner or later, you start thinking about how nice it would be if you had an oscilloscope.

For me it took about nine months. I saw an article on using AVR as an RFID tag and noticed I could build a simple RFID reader with a few components. However, to really learn something, it would be nice to actually see the 125 kHz RFID carrier wave instead of fumbling blindly with the schematics. Additionally, I could use the scope to verify DIY D/A circuits, maybe debug serial protocols and much more. So I started researching.

Getting a used analog or digital scope from eBay was of course one option. However, old scopes are big, clunky and I don’t really have much table space. And if the scope fell out of use, it would be wasting space in a closet. New Chinese-made digital scopes from Owon and Rigol looked good and were relatively small and light. However, they had 640×480 or 800×600 displays and I had 2560×1600 30″ monitor sitting on my workspace, and being more of a software person, I eventually decided against them and chose to get a PC scope instead.

Options in USB scopes

Going through the options for digital scopes, there seemed to be a few price brackets:
