Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional VNA with single chassis is used, then measurement precision is maintained, but measurement capability for distant ports is lost
Solution Approach 1:
The VNA system is divided into multiple independent single-port VNA modules that can be physically separated and distributed to different locations. Each module contains complete measurement functionality (source, receiver, processor), allowing them to operate autonomously while maintaining measurement precision through modular design. This segmentation enables measurement of distant ports while preserving accuracy through synchronized operation.
Solution Approach 2:
Multiple single-port VNA modules are combined to function as a unified multi-port VNA system. The modules are synchronized through a common time reference and coordinated control to operate together, effectively merging their capabilities to provide both extended measurement range and maintained precision through collective operation.
2Adaptability or versatility
If VNA ports are separated by large distances, then adaptability for remote measurement is improved, but synchronization and calibration difficulty increases
Solution Approach 1:
The system implements feedback mechanisms where each VNA module continuously monitors and adjusts its operation based on synchronization signals from other modules. Calibration feedback loops are established between distributed modules, allowing automatic adjustment of phase and amplitude references to maintain measurement accuracy despite physical separation and environmental variations.
Solution Approach 2:
A common time reference and control system acts as an intermediary between distributed VNA modules, coordinating their operation and providing synchronization signals. This intermediary infrastructure manages the complexity of inter-module communication and calibration, allowing modules to operate independently while maintaining system-wide coherence.
3Adaptability or versatility
If multiple single-port VNA modules are used, then remote measurement flexibility is improved, but system complexity increases
Solution Approach 1:
Each single-port VNA module is designed as a universal, self-contained unit that can independently perform complete vector network analysis measurements. The modules share standardized interfaces and protocols, allowing them to be interconnected in various configurations (2-port, 4-port, or more) without requiring different hardware designs, thereby reducing overall system integration complexity.
