What are the uses of Cathode Ray Oscilloscope?

A cathode ray oscilloscope is an instrument that is used to measure common waveform. Suppose you sing a song through a microphone by connecting in CRO, you can get a waveform of your voice.

In physics we have to use CROs for many purposes, usually, we want the frequency of voltage from the electronic circuits.

CRO consists of an electron gun assembly, an anode assembly, and a pair of horizontal deflecting plates.

Hartley oscillator, Colpitt’s oscillator, Phase shift oscillator, Wien’s Bride oscillator and many oscillator electronics circuits are in much need of CRO. We can calculate voltage from the waveform.

We build electronic circuits for instance any oscillator like the Hartley oscillator, and the output of the circuit is connected to CRO. We can easily get the result of that circuit in the waveform. We can able to trace that waveform from CRO and measure the voltage of frequency. Usually, CRO is a voltage-dependent instrument.

What are the uses of a Cathode Ray Oscilloscope?

CRO is mainly used to observe waveforms. CROs are available in both megahertz and gigahertz.

CROs are used to measure the voltage (both AC and DC) of any frequency within the range.

We cannot able to measure the current through CRO directly. But we can measure current through the calculation of resistance and voltage.

We can able to measure simple harmonic motion waveforms.
