The DMC MIL-STD 461 from Diamond Microwave Chambers is a Semi-Anechoic Chamber that operates over a frequency range of 30 MHz to 40 GHz. It is designed for testing in accordance with Mil-STD 461E, Mil-STD 461F, and Mil-STD-461G standards. This chamber is made of DMC-PAN series self-standing shielding, ferrite tiles and Polypropylene based hybrid absorbers on all walls and ceiling with the reflective ground plane. It has a normalized site attenuation (NSA) better than ±3.5 dB and a sVSWR deviation better than ±5.5 dB. This chamber has a field uniformity deviation better than 6 dB at 75% of 16 measuring points from 26 MHz/80 MHz to 18 GHz. It is fully compliant for immunity testing according to IEC/EN 61000-4-3 specification and fully compliant for emission testing per ANSI C63.4 and CISPR-16 specifications. This chamber has an external dimension of 5.5 x 5.5 x 3.5 m and has a load capacity of over 1500 kg.
