Measuring-Channel Synchronization Using Phase-Corrected Clock Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synchronization methods in mobile-radio systems are inadequate, as they lack the necessary accuracy of less than 10 nanoseconds, which is required for modern measurement techniques.
Innovation Solution
A method for synchronizing measuring-channel assemblies and devices using a clock signal generator connected via identical coaxial cables, with phase-corrector elements and phase detectors to ensure identical phase positions, and a system-synchronization signal for inter-device synchronization, allowing for precise phase correction and synchronization across multiple devices and channels.

Engineering Contradiction Analysis
1Measurement precision
If a single clock signal is distributed to multiple measuring-channel assemblies, then synchronization accuracy is improved, but the complexity of the synchronizing device increases due to additional connecting lines and phase-corrector elements
Solution Approach 1:
The patent divides the synchronization system into multiple independent measuring-channel assemblies, each with its own phase-corrector element. This segmentation allows each channel to be synchronized independently while maintaining overall system synchronization accuracy without requiring a completely centralized complex control system.
Solution Approach 2:
The patent introduces phase-corrector elements as intermediary components between the central clock signal source and each measuring-channel assembly. These intermediaries automatically adjust phase differences without requiring complex manual control, thereby improving synchronization accuracy while limiting the increase in overall device complexity.
2Measurement precision
If phase correction is performed for each measuring-channel assembly, then measurement precision is improved, but the device complexity increases due to additional phase-corrector elements and control mechanisms
Solution Approach 1:
The phase-corrector elements in each measuring-channel assembly automatically adjust their own phase without requiring external manual intervention. The system performs self-synchronization by using the phase detector to compare signals and the phase-corrector to automatically compensate for phase differences, thereby improving measurement precision while keeping the complexity increase manageable through automation.
Solution Approach 2:
The patent implements a feedback mechanism where the phase detector continuously monitors the phase difference between the clock signal and the assembly clock signal, and feeds this information back to the phase-corrector element. This closed-loop feedback system automatically maintains synchronization accuracy without requiring complex external control mechanisms.
3Measurement precision
If multiple measuring devices are synchronized using a common timing point, then measurement precision is improved, but the complexity of coordinating multiple devices increases
Solution Approach 1:
The patent designs the synchronizing device with universal functionality that can coordinate multiple measuring devices through a common timing point. The phase-corrector elements and phase detectors are designed to work both within single devices and across multiple devices, allowing the same basic mechanism to handle both intra-device and inter-device synchronization without requiring separate complex coordination systems.
Data Source
AI summary
A method and a measuring device for synchronizing measuring channel assemblies are provided. A reference signal is produced by a reference signal source. The reference signal is supplied to the individual measuring channel assemblies of the measuring device. A clock signal generator is used to produce a clock signal at a low frequency, the clock signal generator being connected to each measuring channel assembly by a respective connecting line of the same length. The clock signal is supplied through a phase corrector element for the purpose of correcting the phase of the reference signal in each measuring channel assembly to the phase of the clock signal.
