What is a Digital oscilloscope?

An oscilloscope is a measuring instrument that observes changes in electrical signals over time. Unlike a tester that only measures the voltage and current at a certain point in time, an oscilloscope can observe the period / frequency of electrical signals, the rising situation, and the time difference / phase difference between multiple signals. Oscilloscopes are roughly divided into digital oscilloscopes and analog oscilloscopes. While analog oscilloscopes project electrical signals onto cathode ray tubes in real time, digital oscilloscopes collect information as "points" obtained by sampling electrical signals at discrete time intervals to create pseudo-waveforms.

Application of Digital oscilloscope

Oscilloscopes can observe electrical signals such as voltage, current, and frequency in electric circuits as waveforms with the time axis as the horizontal axis, so they have been developed for all electric circuits installed in industrial equipment and consumer equipment. It is used for operation verification / debugging at the time, failure analysis after product shipment, etc. Digital oscilloscopes have the disadvantage of lacking real-time performance compared to analog oscilloscopes because they process electrical signals and then convert them into waveforms. Nowadays, digital oscilloscopes are overwhelmingly used.
