In antenna measurement and EMC testing, changing polarization orientation is a routine yet time-consuming task. Traditional methods often require manually disconnecting, rotating, and reconnecting the antenna — a process that introduces mechanical wear, alignment errors, and significant downtime.
RFMiso’s Rotating Polarization Switching Device offers a smarter approach. Designed to seamlessly integrate with horn antennas, it enables rapid, repeatable switching between 45° and 90° (horizontal/vertical) polarization states — and now, with the option for full motorized control, it sets a new standard for test automation.
Key Features
•Dual Polarization Angles: Supports quick switching between 45° and 90° (horizontal/vertical) polarization to meet diverse testing requirements.
•Manual or Motorized Operation: Choose manual rapid positioning for hands-on control, or upgrade to motorized automation for fully programmable operation.
•Precision Mechanical Positioning: Locking mechanisms ensure high repeatability, eliminating human error and enhancing data consistency.
•Plug-and-Play Integration: Compact design allows easy installation between the antenna feed and the horn without system modification.
Why Choose Motorized Automation?
Integrating a motorized drive transforms this device from a convenience tool into a core component of an automated test system. Key benefits include:
•Fully Automated Test Sequences: Program polarization switching as part of a complete measurement sequence — ideal for unattended operation, long-duration testing, or production environments.
•Remote Control & Synchronization: Control the device via standard interfaces, enabling seamless integration with network analyzers, signal generators, and test software for synchronized data acquisition.
•Enhanced Precision & Repeatability: Motorized positioning eliminates manual handling variability, ensuring polarization angles are set with exact precision every time.
•Increased Throughput: Dramatically reduce test time by automating polarization sweeps — essential for applications like antenna pattern measurement, cross-polarization characterization, and EMC compliance testing.
