What are Robotic Near Field Scanners?

Robotic Near Field Scanners are used in EMC testing to automate the process of scanning electromagnetic fields over a defined area with high precision and repeatability. These systems integrate multi-axis robotic arms or gantry-based positioning platforms with near-field probes to perform detailed measurements of electric and magnetic fields close to electronic circuits. By automating probe movement, they enable consistent data acquisition and significantly reduce measurement time compared to manual scanning methods.

These systems are capable of generating high-resolution spatial maps of electromagnetic emissions, allowing engineers to identify hotspots, leakage paths, and coupling mechanisms at the component and PCB level. Key performance parameters include scan resolution, positioning accuracy, repeatability, frequency range, and measurement sensitivity. The use of robotic positioning ensures precise control over probe height and orientation, which is critical for obtaining reliable and repeatable near-field measurements.

Robotic Near Field Scanners are typically integrated with spectrum analyzers, EMI receivers, or vector network analyzers to capture and analyze the frequency content of the measured signals. Advanced software platforms provide 2D and 3D visualization, time-domain analysis, and automated reporting. Some systems also support correlation with design files and simulation data, enabling deeper insight into electromagnetic behavior and aiding in design optimization.

Robotic Near Field Scanners are widely used in advanced EMC diagnostics, PCB design validation, semiconductor development, automotive electronics testing, aerospace systems design, and research environments. They are particularly valuable in complex and high-speed designs where precise identification of emission sources is critical. Their ability to deliver automated, high-resolution, and repeatable measurements makes them a powerful tool for improving EMC performance and reducing time to compliance.
