An EMC (Electromagnetic Compatibility) chamber monitoring system is a precision instrumentation suite designed to measure, analyze, and document electromagnetic emissions and immunity within shielded test environments. These systems integrate broadband antennas, field probes, and spectrum analyzers to capture real-time data across frequencies from 9kHz to 40GHz, ensuring compliance with standards like CISPR 16-2-3 and IEC 61000-4-21. Advanced models incorporate fiber-optic signal transmission to avoid interference, coupled with temperature/humidity sensors to maintain chamber stability during MIL-STD-461G testing. Core components include automated turntables for 360° device under test (DUT) rotation, software-defined radios (SDRs) for adaptive signal detection, and AI-driven anomaly alerts to flag non-conformance during automotive or aerospace certification cycles.
