Cathode Ray Tube – CRT It is the ‘heart’ of an oscilloscope and is very similar to the picture tube in a television set. Construction of CRT The cross-sectional view of a general purpose electrostatic deflection CRT is shwon in Fig. 1. Its four major components are:- As shown, a CRT is a self-contained unit
Cathode Ray Oscilloscope – CRO It is generally referred to as oscilloscope or scope and is the basic tool of an electronic engineer and technician as voltmeter, ammeter and wattmeter are those of an electrical engineer or electrician. The CRO provides a two-dimensional visual display of the signal wave-shape on a screen thereby allowing an
