Cathode Ray Oscilloscope (CRO)

A Cathode Ray Oscilloscope (CRO) is a scientific instrument used to visualize and analyze electrical signals. It displays voltage changes over time on a screen, allowing engineers and scientists to observe waveforms, measure signal amplitude, frequency, and phase. Inside, it uses an electron beam directed at a phosphor-coated screen to create a visible trace. CROs are essential for troubleshooting electronic circuits, studying signal behavior, and designing electronic systems. They provide real-time, detailed insights into how electrical signals behave, making complex signals easier to understand and analyze.
