DPO and development of oscilloscope technology
The application of digital fluorescence display technology enables DPO to simultaneously display multiple images of signals in different shades or colors. DPO clock can record 200,000 waveforms per second, and its signal data is 1000 times more than ordinary DSO, and each time can capture 500,000 waveforms. This fast waveform acquisition rate combined with excellent display ability enables DPO to analyze any detail of the signal.
Usually DSO for processing display data in the display between two waveforms have 8 ms dead time, even if the sampling technologies adopted instavuTM DSO this time also can reduce to 1.7 mu s, ART cannot capture the waveform oscilloscope in flyback time information and DPO can always at the highest sampling rate of continuous sampling of hundreds of thousands of waveforms, overcome the other between stagnation into the problems of the oscilloscope. The sampling rate of DPO generally has several 109 times per second, which allows oscilloscope to have larger bandwidth.
The essence of oscilloscope
What is the essence of an oscilloscope?Indeed, features such as display resolution, brightness, and ease of use are a must, as are sampling speed, triggering, and bandwidth. Some digitizers provide most of the features, but are best represented as data acquisition systems or transient recorders.Some oscilloscopes do not offer all of these features, but they are clearly still oscilloscopes, albeit slow or difficult to use.

The telecommunications dictionary defines a digitizer as a device that converts an analog signal into a digital representation, usually by sampling the analog signal at a specified rate and encoding each sample into a digital representation of the sample amplitude.
The dictionary defines an oscilloscope as a device capable of displaying waveforms and other information on a cathode-ray tube such as a television.An oscilloscope is fundamentally different from a digitizer in that it is an analog instrument for testing.Waveform display is the most important factor.
A digitizer is an embedded module, such as one controlled by a system computer in a VXI bus or similar test system.Small digitizers embedded in physical and electrical laptops provide similar performance to oscilloscopes, but the virtual user interface is not as easy to understand and use as the actual knobs and buttons.However, data analysis and reports are done in the same instrument, and the digitized waveform is displayed on the digital screen.
