Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an external signal is applied to measure operating characteristics, then measurement can be performed, but measurement efficiency and accuracy deteriorate
Solution Approach 1:
The signal generator performs self-measurement by using its own output signal as the stimulus and measuring the reflected signal at its own output port. The correction parameter measurement unit is integrated into the signal generator housing, allowing the device to measure its own operating characteristics without requiring external measurement equipment or signals.
2Productivity
If separate measurement equipment is used, then measurement can be performed, but measurement efficiency deteriorates
Solution Approach 1:
The correction parameter measurement unit is integrated into the signal generator housing, merging the signal generation function and the measurement function into a single device. This eliminates the need for separate measurement equipment and external signals, thereby improving both measurement efficiency and accuracy.
3Measurement precision
If correction parameters are not measured, then device complexity is reduced, but measurement accuracy deteriorates
Solution Approach 1:
The signal generator is designed with multi-functionality, serving both as a signal source and as a measurement device. The correction parameter measurement unit enables the device to perform both signal generation and self-characterization, eliminating the need for separate measurement equipment and external signals.
