The TEK-Near Field Scanner from Tekiknow Technologies India Pvt. Ltd. is a Robotic Field Scanner that is designed for circuit design and electronic troubleshooting. It can perform real-time measurement and efficient fault diagnosis for the design and pre-qualification phases. This scanner can be controlled via Ethernet, GPIB, USB, and RS232 interfaces. It can execute 3D graphical visualization via NFS Viewer, and automated vector measurements for fast, detailed insights. This NF Scanner reduces testing time, locates localized disturbances, and ensures compliance with EMC specifications. It enables detection of emission problems early, analyzes product performance, checks shield leakage, evaluates PCB track impedance, and optimizes component placement to minimize self-disturbance.
