adrienne said:what is the use of AC-GND-DC switch??
wt will happen on the screen if a dry cell is connected to the CRO with AC-GND-DC button switched to AC?? then wt will happen if GND is on??
A cathode ray oscilloscope (CRO) is a scientific instrument used to measure and display electrical signals. It works by using an electron beam to display the signal on a screen, allowing for visual analysis of the waveform.
A CRO has three main components: an electron gun, deflection plates, and a fluorescent screen. The electron gun produces a beam of electrons, which is directed by the deflection plates to create a trace on the screen. The signal being measured controls the intensity and position of the electron beam, creating a visual representation of the signal.
CROs are used in a variety of fields, including electronics, telecommunications, and medicine. They are commonly used to troubleshoot electronic circuits, analyze waveforms, and measure electrical signals. In medicine, CROs are used to measure and monitor biological signals, such as ECGs and EEGs.
CROs offer several advantages over other types of measuring instruments. They provide a visual representation of the signal, making it easier to analyze and troubleshoot. They also have a wide frequency range and high precision, allowing for accurate measurements of fast-changing signals.
While CROs have many advantages, they also have some limitations. They can only measure electrical signals and are not suitable for measuring physical quantities such as temperature or pressure. They also have a limited bandwidth, meaning they cannot accurately measure signals with frequencies above their specified range.
