Engineering Contradiction Analysis
1Measurement precision
If manual configuration of signal generator circuit is performed, then optimization precision can be achieved, but user expertise requirement increases significantly
Solution Approach 1:
The signal generator circuit automatically optimizes its own configuration parameters through a feedback mechanism. The control circuit determines performance parameters based on the RF output signal and automatically adapts operational parameters without requiring manual intervention, enabling the system to serve itself and eliminate the need for expert user configuration
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where the control circuit continuously monitors the RF output signal, determines performance parameters (such as EVM or ACLR), and automatically adjusts operational parameters based on this feedback to optimize test precision while simplifying operation
2Ease of operation
If automatic optimization is implemented, then ease of operation improves, but system complexity increases
Solution Approach 1:
The control circuit performs multiple functions including determining performance parameters, analyzing RF output signals, and automatically adapting operational parameters within a single integrated unit. This multi-functionality consolidates what would otherwise require separate circuits, managing system complexity while enabling automatic optimization
Solution Approach 2:
The patent combines the performance determination function and the parameter adaptation function into an integrated control circuit that processes RF output signals and automatically adjusts operational parameters. This merging of functions simplifies the overall system architecture compared to having separate independent circuits for each function
