Oscilloscope Video Tutorial - How to use a scope made easy

[Alan]

A scope is something that can help you design and troubleshoot your circuits. When you get a bit serious about electronics you should get yourself one. I would suggest your first one be a sub $100 model to get your feet wet, you can move up to a costlier unit when you see the need.
