Solution Overview
Problem
Conventional vector network analyzer calibration methods are time-consuming, expensive, and prone to errors due to manual handling and wear of connections, and often require standards similar to the device under test, which may not exist.
Innovation Solution
A fully automated calibration system using motorized and non-motorized calibration components connected by a connector positioner system, eliminating the need for manual replacement and ensuring reliable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of calibration components is used, then calibration can be performed with flexibility, but calibration time increases and errors are introduced
Solution Approach 1:
The calibration system performs self-calibration automatically without requiring manual intervention. The connector positioner system autonomously connects calibration components to the VNA ports, and the controller automatically executes calibration routines, eliminating the need for operator involvement in the calibration process.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated connector positioner system. The positioner system uses motorized or automated mechanisms to connect calibration components to VNA ports, substituting the manual mechanical connection process with an automated control system that reduces time and eliminates human error.
2Adaptability or versatility
If manual handling of calibration components is performed, then calibration can be adapted to different standards, but connection errors are introduced due to wear and variability
Solution Approach 1:
The connector positioner system autonomously manages the connection of calibration components, ensuring consistent and reliable connections every time. The system self-regulates the connection process without human intervention, eliminating variability in torque, contact pressure, and alignment that occurs with manual handling.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor and adjust connection parameters. The controller receives feedback from the connector positioner system about connection status and quality, allowing real-time adjustments to ensure optimal connection reliability across different calibration standards.
3Productivity
If automated connector positioner system is used, then calibration time is reduced and errors are avoided, but device complexity increases
Solution Approach 1:
The connector positioner system is designed as a multi-functional device that can handle multiple calibration components and connect them to different VNA ports. This universal design consolidates what would otherwise require multiple separate manual operations into a single automated system, reducing overall complexity despite the automation itself.
Solution Approach 2:
The patent merges the connector positioner system, controller, and calibration component handling into an integrated automated calibration system. By combining these functions into a unified system rather than separate components, the overall complexity is managed more efficiently while achieving high productivity.
