It is flat for screen sizes up to about 100mm * 100mm and is slightly curved for larger displays. The front of the CRT is called the faceplate. The Plates are flared so as to allow the beam to pass through them without striking the plates. The other pair of plates is called “Horizontal Deflection Plates or X-Plates”. This pair produces a vertical deflection and is thus called “vertical deflection plates or Y-plates”. one pair of plate is mounted horizontally and produces an electric field in the vertical plane. This explain the working of cathode ray oscilloscope the electron beam, after leaving the electron gun, passes through two pairs of deflection plates. This focused beam of electrons strikes the fluorescent screen with high energy to cause a luminous spot on the screen. The “electron gun assembly” produces a sharply focused beam of electrons which are accelerated to high velocity. Construction of Cathode Ray OscilloscopeĬathode Ray Oscilloscope cosists of a cathode ray tube (CRT), which is the heart of the tube. however, it is possible to convert current, strain, acceleration, pressure and other physical quantities into voltages with the help of transducer. Cathode ray oscilloscope operate on voltages. cathode ray oscilloscope are also used to investigate waveforms, transient phenomena, and other time varying quantities from a very low frequency range to the radio frequencies. cathode ray oscilloscope are used infect very fast X-Y plotters, displaying an input signal versus another signal or input signal versus time. ![]() It is very useful & versatile laboratory instrument used for display, measurement and analysis of waveforms and other phenomena in electrical and electronics circuits. Working Principle of Cathode Ray OscilloscopeĬRO stands for Cathode Ray Oscilloscope. ![]() Construction of Cathode Ray Oscilloscope.Introduction of Cathode Ray Oscilloscope.
