The EM-Isight Scanning System offers five or six axes of articulated robotic movement which can perform near-field analysis on PCBs, wireless handsets, and antennas. Measurements are made using an IEC-61967 magnetic probe feed into a standard spectrum analyzer. Features include effective correlation to standard EMC measurement methodologies, real-time data visualization tools, and complete distribution of the fields presented in a 3-D plot. 4-D measurements are achieved using X, Y, Z, and PHI movements. The dynamic range is dependent on environmental conditions and spectrum analyzer type; the integrated low-noise preamplifier provides an additional 28-dBm gain. The system can be located on a standard workbench and runs on Windows XP/Vista/Win7.
