The oscilloscope's deflection system is mostly electrostatically deflected. It consists of two pairs of mutually perpendicular parallel metal plates, called horizontal deflection plates and vertical deflection plates. Control the movement of the electron beam in the horizontal and vertical directions, respectively. When electrons move between the deflection plates, if no voltage is applied to the deflection plates, there is no electric field between the deflection plates, and electrons entering the deflection system after leaving the second anode will move axially toward the center of the screen. If there is a voltage on the deflection plate, there is an electric field between the deflection plates, and electrons entering the deflection system will be directed to the designated position of the phosphor screen by the deflection electric field.
If the two deflecting plates are parallel to each other and their potential difference is equal to zero, the electron beam having the velocity Ï… passing through the deflecting plate space moves along the original direction (set as the axial direction) and hits the coordinate origin of the fluorescent screen. . If there is a constant potential difference between the two deflecting plates, an electric field is formed between the deflecting plates. This electric field is perpendicular to the direction of movement of the electrons, so that the electrons are deflected toward the deflecting plate having a relatively high potential. Thus, in the space between the two deflecting plates, the electrons are tangentially moved along the parabola at this point. Finally, the electron falls on point A on the screen. This point A is a distance from the origin (0) of the screen. This distance is called the amount of deflection and is represented by y. The amount of deflection y is proportional to the voltage Vy applied to the deflection plate. Similarly, when a DC voltage is applied to the horizontal deflection plate, a similar situation occurs, except that the spot is deflected in the horizontal direction.
