![]() ![]() What is meant by the deflection sensitivity of a CRO? The hole in a grid of a CRO is provided to allow passage for electrons through it and concentrate the beam of electrons along the axis of the tube.Ĩ. Why is the grid in a CRO provided with a hole in it? The sole function of an electron gun assembly in a CRO is to provide a narrow and sharply focused electron beam with is accelerated towards the phosphor screen.ħ. What electron gun assembly is provided in CRT? The essential components of a CRT are electron gun, focussing and accelerating anodes, horizontal and vertical deflection plates, and evacuated glass envelope with phosphorescent screen.Ħ. What are the essential components of a CRT? In a CRO, a triggering circuit is provided for synchronising two types of deflections so that horizontal deflection starts at the same point of the input vertical signal each time it sweeps.ĥ. For what a triggering circuit is provided in a CRO? Horizontal and vertical plates are provided between electron gun and screen to deflect the beam according to the input signal.Ĥ. For Explain what vertical and horizontal plates are provide in a CRO? It is also from damping mechanisms and other inertia containing parts.ģ. The CRO gives very accurate measurements and is free from the errorsintroduced by the moving parts. ![]() How is CRO superior to ordinary measuring instruments?ĬRO is an electronic device that gives graphical representation of alternating quantities under examination. ![]() What is a cathode ray oscilloscope (CRO)?Ī CRO is an electronic device with a CRT as its main component and other associated circuits consisting of a power supply unit, a sawtooth-wave generator, horizon and vertical amplifiers.
