Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed trigger criteria are used for dual-trigger oscilloscope, then the device complexity is reduced and operation is simplified, but the adaptability to analyze different waveform portions is limited
Solution Approach 1:
The patent implements dynamic trigger criteria that automatically adjust between triggered acquisitions. The system transitions from fixed, manual trigger definitions to dynamically reconfigurable trigger criteria that adapt based on waveform characteristics, enabling simultaneous analysis of different waveform portions without manual intervention.
Solution Approach 2:
The oscilloscope system performs self-configuration of trigger criteria by automatically analyzing captured waveforms and adjusting trigger parameters. The system scans acquired information and autonomously modifies trigger settings, eliminating the need for manual user reconfiguration and enabling adaptive waveform analysis.
2Productivity
If manual reconfiguration of trigger criteria is required between acquisitions, then the device complexity is reduced, but the productivity and analysis efficiency are decreased
Solution Approach 1:
The system automatically scans acquired waveform information and reconfigures trigger criteria without user intervention. This self-service capability enables rapid adaptation between acquisitions, significantly improving productivity by eliminating manual reconfiguration steps and allowing continuous automated waveform analysis.
Solution Approach 2:
The system implements a feedback loop where acquired waveform data is scanned and analyzed, and this information feeds back into automatic trigger criteria adjustment. The trigger settings are dynamically modified based on feedback from waveform analysis, enabling rapid adaptive analysis across multiple acquisitions.
3Measurement precision
If fixed A- and B-Event definitions are used, then the ease of operation is improved, but the measurement precision for capturing different waveform portions is limited
Solution Approach 1:
The oscilloscope automatically determines optimal A- and B-Event definitions by scanning acquired waveform data. This self-service approach maintains ease of operation with simple initial setup while achieving high measurement precision through automatic adaptation of trigger event definitions based on actual waveform characteristics.
Solution Approach 2:
The system dynamically changes trigger parameters including A- and B-Event definitions, sequence relationships, and placement positions. These parameter changes enable precise capture of different waveform portions while maintaining operational simplicity through automated parameter optimization based on waveform analysis.

AI summary
A test and measurement instrument includes an input terminal to receive a signal, acquisition circuitry to capture a plurality of triggered acquisitions, trigger circuitry to cause a trigger event responsive to trigger criteria, and a controller to dynamically reconfigure the trigger criteria between triggered acquisitions. The controller is configured to dynamically reconfigure the trigger criteria from the first set of trigger criteria to subsequent sets of trigger criteria between each of the triggered acquisitions. A method is disclosed for scanning information associated with an initial triggered acquisition and, depending on the nature of the scanned information, dynamically adjusting the next or any subsequent set of trigger criteria.
