![]() ![]() The electron gun generates the beam of an electron when the voltage is applied to it. The cathode ray tube consists of an electron gun, vertical deflection plates, horizontal deflection plates, phosphor screen and electrode. ![]() We will start with cathode ray tube which is the backbone of Oscilloscope. Let’s discuss these parts one by one in detail. Let’s discuss what are those parts which made up a device which can generate the waveform. To understand the block diagram more clearly we need to focus on its major parts. The functionality of Oscilloscope can be interpreted more easily with the help of its block diagram. These electrical quantities are expressed in terms of voltage and current which can be easily measured with the help of oscilloscope.įor waveshaping applications, an oscilloscope is considered very significant as any kind of waveforms can be generated with the help of Oscilloscope. But their physical appearance does not provide a single basis to measure such quantities.įortunately, the invent of transducers has alleviated this problem, as with the help of it any physical quantity can be converted into an electrical quantity. This is because in the realm of instrumentation we deal with measurement of physical quantities such as pressure, temperature, displacement. The non-electrical quantities can also be measured with the help of Oscilloscope, but we need to convert it in electrical form before applying it to input terminals of Oscilloscope because only electrical quantities can be given as an input to the Oscilloscope.Ĭathode ray Oscilloscope is considered to be the heart of electronics instrumentation.
