How Does Analog and Digital Oscilloscope Work?
To know more about how an oscilloscope works, you have to understand how it detects and shows a signal. The analog type is different from the digital one. The analog type of oscilloscope is much simpler than digital oscilloscope. We will talk about the analog type and then the digital type. The voltage signal of an analog oscilloscope runs to the vertical system. The vertical system is used to control the amplitude of a signal. The increasing of a signal voltage is depending on how the vertical scale is set. The signal then transferred to the cathode ray tube. When an electron hits the phosphor inside cathode ray tube, it creates glowing dot that is moved by voltage which is applied to deflection plates. The signal sent also goes to the trigger system. It causes the horizontal time base to move the dot on the screen. It moves from left to right in specific interval. The frequent speeds results in the glowing dot to form a solid line. The sweeping action and the vertical deflection acti
