Using scopes is simple, they merely provide for graphic representation of the waveshape of signal. One simply connects it go the signal and then watches it. Usually the user knows what general shape to expect and so sets up the vertical (V/div) and horizontal (time scale, sec/div) scales accordingly.
The gist is in understanding what the waveshape means. And that goes way beyond the usage of scopes.

Same goes for every measuring device: a DMM, an EKG, MRI, etc. This is why learning basics is to me way more important than learning tools.
