The ultimate debugging tool for electronics, this oscilloscope will turn you into a "Circuit Whisperer". You will be able to peer into the workings of your circuits to better understand them. Difficult problems will suddenly become trivial. We tried many beginner oscilloscopes and found this one to be a perfect balance of price and function: it's perfect as a 'first scope' or as a hacker-space resource to share. To learn about how to use oscilloscopes, we suggest reading Tektronix's great "XYZs of Oscilloscopes" and the other great Tek documents that cover everything you need to know!
