Classification Of Oscilloscope Instruments

Oscilloscopes can be divided into analog oscilloscopes and digital oscilloscopes. For most electronic applications, both analog and digital oscilloscopes are competent, but for some specific applications, due to the different characteristics of analog and digital oscilloscopes, there will be suitable and unsuitable places.
Analog
The working mode of an analog oscilloscope is to directly measure the signal voltage and plot the voltage in a vertical direction using an electron beam passing through the oscilloscope screen from left to right.
digital
The working mode of a digital oscilloscope is to convert the measured voltage into digital information through an analog converter (ADC). A digital oscilloscope captures a series of sample values of a waveform and stores them until it determines whether the accumulated sample values can depict the waveform. Subsequently, the digital oscilloscope reconstructs the waveform.
Digital oscilloscopes can be divided into digital storage oscilloscopes (DSOs), digital fluorescence oscilloscopes (DPOs), and sampling oscilloscopes.
In order to improve the bandwidth of analog oscilloscopes, it is necessary to comprehensively promote oscilloscope tubes, vertical amplification, and horizontal scanning. To improve the bandwidth of a digital oscilloscope, it is only necessary to improve the performance of the front-end A/D converter, and there are no special requirements for the oscilloscope tube and scanning circuit. In addition, digital oscilloscope tubes can fully utilize memory, storage, and processing, as well as various triggering and advanced triggering capabilities. In the 1980s, digital oscilloscopes sprang up, with numerous achievements, and there was a great potential to replace analog oscilloscopes comprehensively. Analog oscilloscopes did indeed retreat from the foreground to the background
