Comprehensive Overview of RF/EMC Testing in Anechoic Chamber (300 MHz - 6 GHz)

This report, authored by Chih-Ching Chen and Chris Yao, discusses the specifications and requirements for conducting RF and EMC tests in an anechoic chamber designed for frequencies between 300 MHz and 6 GHz. The chamber measures 6m x 6m x 12m, equipped with a turning table and various essential equipment, including horn antennas, pulse generators, and oscilloscopes. Critical considerations such as chamber size, antenna weight, and absorber materials are addressed to ensure accurate testing outcomes. The report highlights the importance of proper setup and measurement techniques for optimal results.
