Engineering Contradiction Analysis
1Measurement precision
If a user manually specifies a zoom window for high zoom factors, then the precision of position selection can be improved, but the time required for configuration increases significantly
Solution Approach 1:
The system automatically determines the zoom window position and dimensions based on the overview waveform before the user finalizes the zoom operation. This preliminary automatic positioning eliminates the need for multiple manual adjustment attempts, providing precise position selection while reducing configuration time.
Solution Approach 2:
The measurement device performs self-adjustment by automatically calculating the optimal zoom window parameters (position, width, height) based on the signal characteristics visible in the overview. The system serves itself by detecting signal features and autonomously configuring the zoom window without requiring extensive manual intervention.
2Measurement precision
If multiple input elements are used for specifying zoom parameters, then the precision of zoom window specification can be improved, but the device complexity increases
Solution Approach 1:
The system automatically determines the optimal zoom window parameters by analyzing the overview waveform and signal characteristics. This self-service approach eliminates the need for multiple manual input elements (rotary knobs, numerical inputs), reducing operational complexity while maintaining precise zoom window specification through automated calculation of position, width, and height based on visible signal features.
3Ease of operation
If the vertical zooming is manually adjusted, then the user can control the visualization details, but the time required for configuration increases
Solution Approach 1:
The system performs preliminary automatic vertical zooming adjustment by analyzing the signal amplitude range within the selected horizontal zoom window. Before the user completes the zoom operation, the system pre-calculates and applies the appropriate vertical scale to ensure the waveform is optimally displayed, eliminating the need for manual vertical adjustment and reducing configuration time.
Solution Approach 2:
The measurement device automatically adjusts vertical zooming parameters by detecting the minimum and maximum signal values within the zoom window and autonomously setting the vertical scale. This self-service mechanism provides appropriate visualization control without requiring manual intervention, thereby reducing configuration time while maintaining ease of operation.
