Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional RF test equipment is used, then testing can be performed with established methods, but the equipment is expensive and easily rendered obsolete due to evolution of new RF technologies
Solution Approach 1:
The system dynamically adapts to new RF technologies by allowing remote updates of test algorithms and parameters through the communication interface. The test equipment can be reconfigured via the processor to implement new testing methods without physical hardware changes, enabling continuous adaptation to evolving RF standards and protocols.
Solution Approach 2:
The test equipment is designed with universal functionality to support multiple RF testing scenarios through a single platform. The processor-executable algorithms can be updated to cover different RF technologies and test requirements, making one piece of equipment capable of performing diverse testing functions across various wireless communication standards.
2Ease of operation
If traditional RF test equipment generates and determines test patterns internally, then testing can be performed autonomously, but the test time is longer and the equipment cannot effectively and quickly update test items and specifications
Solution Approach 1:
Test algorithms and patterns are prepared and stored in advance in the memory device, allowing the processor to quickly execute pre-configured test sequences. This preliminary preparation enables faster testing by eliminating the need for real-time generation of complex test patterns during the actual measurement process.
Solution Approach 2:
A communication interface acts as an intermediary between external systems and the test equipment, enabling rapid updates of test specifications and algorithms. This intermediary channel allows test items and parameters to be quickly modified and transmitted to the processor without requiring physical access or complex reconfiguration procedures.
3Adaptability or versatility
If traditional RF test equipment includes as many test items as possible, then comprehensive testing coverage is achieved, but the computing resources and capabilities are not maximized when required computing resources are not high
Solution Approach 1:
The computing resources are dynamically allocated based on the actual test requirements. The processor can adjust the complexity and intensity of testing algorithms in real-time, scaling computational efforts to match the specific needs of each test scenario, thereby optimizing resource utilization while maintaining comprehensive coverage.
Solution Approach 2:
Test parameters such as algorithm complexity, sampling rates, and processing intensity can be modified to match available computing resources. The system can adaptively adjust these parameters to ensure effective use of computing capabilities while still achieving thorough testing coverage across all necessary test items.
