This gun mainly includes a heater, a grid, cathode, and anodes like accelerating, pre-accelerating & focusing. The main function of the electron gun is to emit the electrons to form them into a ray. Thus, it can amplify the signal to a level that will be provided the deflection of the electron beam. The signals are passed from the vertical deflection plate through the vertical amplifier. Just before detecting the electron beam on the screen in the horizontal direction which is in X-axis a constant time-dependent rate, a time base generator is given by the oscillator. The horizontal and vertical plates are placed between the electron gun and the screen, thus it can detect the beam according to the input signal.

The normal voltage supply is necessary for other control units of the oscilloscope.

A high voltage is required for the cathode ray tube to speed up the beam. The low voltage is used for the heater of the electron gun to generate the electron beam. Here we will use high voltage and low voltage. This provides the power supply circuit of the oscilloscope. To complete this task we need various electrical signals and voltages. By detecting the beam above the screen in reply to the electrical signal, the electrons can act as an electrical pencil of light which produces a light where it strikes. Thus, the screen produces a visible spot where the electron beam strikes with it.
