Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spectral characteristics are measured to determine compliance with communications standards, then measurement coverage is improved, but detailed analysis capability deteriorates
Solution Approach 1:
The patent segments the communications signal into multiple signal components based on spectral characteristics. The selection unit divides the received signal into different signal components according to their spectral properties, enabling detailed analysis of each component while maintaining overall measurement coverage.
Solution Approach 2:
The patent introduces a selection unit as an intermediary between the frequency-mask trigger unit and measurement applications. This selection unit acts as a mediator that automatically identifies and allocates signal components to appropriate measurement applications based on spectral characteristics, preventing information loss while maintaining measurement precision.
2Adaptability or versatility
If multiple communications standards are supported in a base station, then adaptability is improved, but testing complexity deteriorates
Solution Approach 1:
The patent creates a universal testing device that can handle multiple communications standards (GSM, UMTS, LTE) through a single integrated system. The selection unit automatically identifies the standard type and routes signals to appropriate measurement applications, allowing one device to perform multiple testing functions without increasing complexity.
Solution Approach 2:
The testing system performs self-service by automatically identifying signal components and allocating them to the correct measurement applications without manual intervention. The selection unit autonomously determines which standard is being tested and configures the measurement process accordingly, reducing the complexity of multi-standard testing.
3Productivity
If automatic allocation of signal components is implemented, then productivity is improved, but device complexity deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring the selection unit with knowledge of different signal component characteristics and their corresponding measurement applications. This preliminary setup enables automatic allocation to occur without complex real-time decision-making, improving productivity while keeping the allocation mechanism relatively simple.

AI summary
At the start of a method for analyzing a communications signal with a frequency-mask trigger unit and a selection unit, a mask which describes a trigger range for the frequency-mask trigger unit is defined in the frequency domain, in frequency and amplitude. Furthermore, within the selection unit, an application is allocated to the mask. The frequency-mask trigger unit then checks whether the spectrum of the communications signal violates the mask. Finally, the signal component of the communications signal which violates the mask is transferred to the application for a further evaluation by the selection unit.
