The cathode ray oscilloscope is referred to as a CRO. Display, vertical controllers, horizontal controllers, and triggers make up its standard four components. The majority of oscilloscopes use probes, which are used as input devices for all instruments. By charting the amplitude along with the x-axis and y-axis, we can evaluate the waveform.

The main areas where CRO is used are in radio and television receivers, as well as in laboratory activities requiring research and design. The CRO is a crucial component of electronic circuits in modern electronics.

## Answer – A CRO can be Used to Measure Voltage, Frequency, and Phase.

Because of the electrostatic force, the electron ray movement is essential to the CRO functioning principle. A bright spot is created on a phosphor face when an electron ray strikes it. The electrostatic force is applied to the electron ray in two vertical directions by a cathode ray oscilloscope. Due to the interaction of these two electrostatic forces, which are mutually perpendicular, the spot on the phosphor monitor rotates. It moves to create the input signal’s requisite waveform.

The voltage signal is displayed on screens like CRO as if it were a time function. The signal’s amplitude is consistent, but using the volt/division button on top of the CRO board, we can adjust how many divisions are used to conceal the voltage signal in a vertical direction. The CRO may be used to measure electrical quantities like amplitude, time period, and frequency.

Summary:

## A CRO can be Used to Measure

A CRO can be Used to Measure Voltage, Frequency, and Phase. Also, the CRO may be used to measure electrical quantities like amplitude and time period.
