What is the working principle of oscilloscope?

Displaying and analyzing electrical signals in graphical form is the primary function of a laboratory tool known as an oscilloscope . It offers a technique of measuring many characteristics like frequency, amplitude, rise time, and others by displaying signals on a screen as waveforms and displaying them on the screen. The oscilloscope's operation is predicated on the deflection of an electron beam as its fundamental operating principle. The electron beam is generated by a device known as a cathode ray tube, or CRT. A stream of electrons is generated by an electron gun located at the front of the CRT. These electrons are concentrated into a tiny region before being propelled towards the screen by an anode. The X and Y deflection plates are two pairs of electrodes that are situated in a direction that is perpendicular to each other. These electrodes are responsible for deflecting the beam. While the X plates are responsible for deflecting the beam in a horizontal direction, the Y
