Recently picked up an oscilloscope from Adafruit, or wondering what you might use one for if you did have one at your disposal?  Tektronix ‘XYZs of Oscilloscopes‘* gives a great introduction to the basics of scopes, and the content is all pretty much universal.  Having a scope opens up a world of debugging and learning opportunities (seeing is believing!), but the learning curve can be a bit steep if it’s your first time in front of one.  Know any other good tutorials to help people get started?  Feel free to post them in the comments below!

*Note: Registration is required to download any of the primers and guides from Tek, but it’s all free and there really is some good information in the different guides.
