Digital storage oscilloscope.

Digital oscilloscope is the display part of digital storage oscilloscope (DSO) based on raster screen rather than fluorescence. It allows you to capture and display events that may occur only once, often referred to as transient phenomena. In digital form, the waveform information is stored in binary sequence. The waveform is not necessarily continuous; Even if the signal has disappeared, it can still be displayed. The digital storage oscilloscope can retain the signal persistently and can extend the waveform processing mode. However, DSO does not have a real-time brightness level; Therefore, they cannot represent different levels of brightness in actual signals. Some of the subsystems that make up DSO are similar to those of analog oscilloscopes. However, DSO contains more data processing subsystems, so it can collect data showing the entire waveform. From capturing signals to displaying waveforms on the screen, DSO USES a serial processing architecture.

Serial processing architecture.

Like an analog oscilloscope, the first part of DSO (input) is a vertical amplifier. At this stage, the vertical control system is convenient for you to adjust the range and position range. Next, in the ADC part of the horizontal system, the signal is sampled at discrete points in real time, and the signal voltage of the sampling location is converted to the digital value, which is called the sampling point. The process is called signal digitization. The sampling clock of the horizontal system determines the frequency of ADC sampling. This rate is called the sampling rate, which represents the sample value per second (S/ S).
