The DMC-SAC-3M-M from Diamond Microwave Chambers is a Shielded, Semi-Anechoic Chamber (SAC) with a frequency from 30 MHz to 40 GHz. It is designed for full-compliance & pre-compliance emissions & immunity testing at a test distance of 3 meters and has a quiet zone diameter of up to 1.5 meters. This SAC is fully compliant with emission standards per ANSI C63.4 and CISPR-16, and immunity standards per IEC/EN 61000-4-3 and ISO 11452. It supports a wide range of EMC test requirements, including CISPR 11, 14, 15, 22, 25, & 32, and MIL-STD 461. This chamber has a Normalized site attenuation deviation (NSA) better than ±3.5 dB from 30 MHz to 1 GHz and a sVSWR deviation better than ±5.5 dB from 1 GHz to 18 GHz. It has a self-standing shielded structure with ferrite tiles and hybrid absorbers based on polypropylene, integrated into all interior walls and ceiling, and a reflective ground plane. This SAC has a footprint of 9.1 x 6.0 x 5.8 m.
