Test Software Server Unit for High-Frequency Signal Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional measuring systems for devices like mobile telephones are costly due to the need for external control computers and interfaces to generate and process high-frequency signals, and they often lack access to all required functions of the device under test.
Innovation Solution
A measuring system comprising a high-frequency processing unit and a test-software server unit that allows the device under test to receive and transmit high-frequency signals, with optional control computer support, enabling complex measurements at minimal cost by installing test-software directly on the device under test.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external control computers and additional interfaces are used to control the device under test, then the device can generate and process high-frequency signals, but the measuring system becomes costly and complex
Solution Approach 1:
The device under test is equipped with test software that enables it to autonomously generate and process high-frequency signals without requiring external control computers or additional interfaces. The device serves itself by executing measurement protocols locally, thereby eliminating the need for costly external control infrastructure while maintaining full measurement capability
Solution Approach 2:
The device under test is designed to perform multiple functions: it acts as both the device being measured and the signal generation/control unit. By integrating test software that enables signal generation, processing, and self-control, the device becomes a multi-functional platform that replaces separate external control computers and interfaces
2Adaptability or versatility
If external control computers are used to access device functions, then control capability is improved, but cost increases significantly
Solution Approach 1:
The device under test executes measurement protocols and controls its own functions through embedded test software, eliminating the need for external control computers. This self-service approach provides full access to device functions while avoiding the high costs associated with external control infrastructure
Solution Approach 2:
The control functionality is extracted from external control computers and integrated directly into the device under test through embedded test software. This extraction eliminates the need for separate external control systems while maintaining complete access to all required device functions
