The pride of your electronics lab is the instrument known as cathode ray oscilloscope (CRO). It is a versatile lab instrument used to visualize waveforms in real time…
To measure the phase different between two waveforms, their frequencies must be same. Connect the two waveforms randomly at x-input and y-input of CRO. Keep time/div knob in x-y mode. Now a Lissajou’s pattern of an ellipse is obtained.
Let us see what is Cathode Ray Tube (CRT)? Explain with diagram CRT. The cathode ray tube is the most important part in CRO. It is made up of thick glass (with vacuum inside) and it is shaped like a funnel. There are number different electrodes inside the CRT.
