Good Morning Usat1987, Welcome to the forum. Near the top of this page is a thread titled:
Oscilloscope training class (long). Lots of good information there and a good place to start. Also TONS of information on the internet if you just Google the word Oscilloscope, including lots of instructional videos. And since you don't have an actual scope yet, there are many, many threads here on the forum, about choosing one when you are ready. Have fun,and enjoy the journey.
