Probe Tip Characterization Data for Precise Measurement Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement probes fail to accurately correct for variations in transmission characteristics among different probe tips, leading to imprecise measurement data.
Innovation Solution
A probe tip module with a reduced characterization data set is used, which includes correction parameters, receiver, and transmitter properties, stored in a smaller memory, allowing for precise correction of measurement data by combining it with a default data set in the probe main module or measurement instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a full characterization data set is stored in the probe tip memory, then measurement precision is improved, but device complexity and memory requirements increase
Solution Approach 1:
The characterization data is segmented into two parts: a reduced characterization data set stored in the probe tip memory and a default characterization data set stored in the measurement instrument. This segmentation allows the probe tip to store only essential correction parameters while the instrument holds the complete reference data, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The essential correction parameters are extracted from the full characterization data set and stored in the probe tip memory, while the remaining default data is kept in the measurement instrument. This extraction enables the probe tip to function with minimal memory requirements while still achieving accurate measurements through combination with the default data set.
2Device complexity
If a reduced characterization data set is used in the probe tip memory, then device complexity is reduced, but measurement precision may deteriorate
Solution Approach 1:
The reduced characterization data set from the probe tip is merged with the default characterization data set from the measurement instrument to form a complete correction data set. This combining ensures that all necessary information for accurate measurement correction is available, preventing any loss of measurement precision despite the reduced memory size in the probe tip.
Solution Approach 2:
The reduced characterization data set acts as an intermediary that provides essential correction parameters to the measurement instrument, which then combines it with the default data set to achieve full measurement precision. This intermediary approach allows the probe tip to have reduced complexity while maintaining measurement accuracy through the collaborative system.
3Measurement precision
If correction parameters are stored in the probe tip module, then measurement precision is improved, but loss of information increases due to limited memory
Solution Approach 1:
The characterization information is segmented into critical correction parameters stored in the probe tip and supplementary default data stored in the instrument. This segmentation ensures that no information is lost, as the complete set of correction data is distributed across both components and combined during measurement correction.
Solution Approach 2:
The system implements a feedback mechanism where the measurement instrument receives the reduced characterization data set from the probe tip, combines it with the default data set, and uses the complete correction information to correct measurement data. This feedback loop ensures that all necessary information is utilized for accurate measurement correction.
