Innovation Solution
A digital oscilloscope system that processes digital video signals to generate oscillogram signals, including oscillogram, menu, and frame image signals, using a data processing system with signal input, frame analysis, oscillogram generation, and video output processing circuits, which outputs the signals to a separate display terminal for intuitive observation, simplifying the oscilloscope structure and enhancing portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional digital oscilloscope with display screen is used, then the oscilloscope can display waveform curves, but the structure becomes complex, size becomes large, and portability is reduced
Solution Approach 1:
The oscilloscope system is divided into two separate parts: the data processing system (oscilloscope core) and the display terminal. The data processing system processes video signals to generate oscillograms, while the display terminal displays the results. This segmentation eliminates the need for an integrated display screen in the oscilloscope, reducing structural complexity and size while maintaining display functionality.
Solution Approach 2:
The display terminal serves multiple purposes: it displays oscillograms, shows menu information, and presents frame images. By using a universal display terminal instead of a dedicated oscilloscope display screen, the system achieves multi-functionality while simplifying the oscilloscope structure.

3Ease of operation
If a conventional digital oscilloscope with display screen is used, then the oscilloscope can display waveform curves, but it cannot adapt to outdoor use scenarios
Solution Approach 1:
The oscilloscope system is divided into two separate parts: the data processing system (oscilloscope core) and the display terminal. The data processing system processes video signals to generate oscillograms, while the display terminal displays the results. This segmentation eliminates the need for an integrated display screen in the oscilloscope, reducing structural complexity and size while maintaining display functionality.
4Device complexity
If a conventional digital oscilloscope with display screen is used, then the oscilloscope can display waveform curves, but the display content is simple and not convenient for intuitive observations
Solution Approach 1:
The display terminal merges multiple types of information into a single comprehensive display: oscillogram images, menu information, and frame images are combined and displayed together. This merging allows users to observe video signal characteristics, control options, and reference frames simultaneously, providing rich and intuitive information without increasing oscilloscope structural complexity.

AI summary
A digital oscilloscope includes a video input interface, a data processing system, a video output interface, and a clock system. The video input interface is configured to receive a digital video signal; the data processing system receives the digital video signal and processes the digital video signal to generate an oscillogram signal, which includes an oscillogram image and further includes one of a menu image and a frame image of the digital video signal; and the video output interface is connected to the data processing system, receives the oscillogram signal and outputs it to external terminals. The oscilloscope can display a variety of image information, with high intuitiveness, simplified structure, improved portability, and is convenient to use in outdoor places.
