Oscilloscope Lab

Overview: 

Today in class, we were shown how oscilloscope work. 

The Data: 

The following is a video of the lecture:

How it works: 

Basically how it works, is there's an electron 'gun' in the back of the CRT tube, which emits electrons towards a glass lens. As the electron flies towards the lens, charge is placed on deflection plates, changing the direction of the electron. What determines when the charge is placed on the deflection plates is the input signal. This means that you can compare two oscillating signals by placing one on the x-axis, and one on the y-axis. Doing so can create some pretty neat geometric shapes, not to mention compare signals quite precisely.
