frequency measurement using cro

Learn how to perform frequency measurement using CRO (Cathode Ray Oscilloscope) with this detailed guide. Our article explains the process step-by-step, utilizing Lissajou’s patterns to accurately measure frequency. With clear diagrams and an easy-to-understand approach, this resource is ideal for students and electronics enthusiasts looking to master frequency measurement techniques using a CRO.

How to measure frequency & phase using Lissajou’s patterns on CRO? Explain with diagrams

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.
