Digital Oscilloscope: An Overview
When it comes to analyzing and troubleshooting electronic circuits, oscilloscopes are an essential tool. An oscilloscope is a device that allows you to visualize electronic signals in real-time. With the advancement of technology, digital oscilloscopes have become the preferred choice for engineers and technicians. In this article, we will take a closer look at digital oscilloscopes, their features, and how they work.
What is a Digital Oscilloscope?
A digital oscilloscope is an electronic test instrument that captures and displays electronic waveforms. It converts the analog signals into digital signals, which can be processed by a microprocessor. The captured waveforms are displayed on a screen, allowing users to analyze and interpret the signals.
How Does a Digital Oscilloscope Work?
A digital oscilloscope works by sampling the analog waveform and converting it into a digital signal. The analog signal is first amplified and then sampled at regular intervals. The samples are then converted into digital values, which are stored in memory. This process is repeated for every waveform, and the stored values are used to reconstruct the waveform on the screen.
