EMC chamber & EMC test system can apply in testing, evaluating EMC to control quality armaments, defence products in military.
1m/3m EMC anechoic chamber, can used to accomplish the standard 1m-distance test as MIL-STD-461F, GJB151/152A, and 3m EMC standard test for civil electronic and electrical products as civil standards GB9254-1998, GB/T17626.3-1998.

Performance of EMC Chamber
Normalized Site Attenuation (NSA): 30MHz~1GHz,meet the requirements of EN50147-2-1996 and ANSIC63.4 1992, NSAJ±4dB. 1~18GHz, meet the requirements of CISPR16-1-4, field voltage standing wave ratio better than 6dB. Field Uniformity(FU): 30MHz~18GHz, meet the requirements of IEC61000-4-3-1995 and EN61000-4-3-1996, i.e., on the 1.5mX1.5m supposed vertical plane surface 0.8m above ground in the EUT zone, with 3 meters test distance, it requires that 75% of the uniformly divided 16 points’ field intensity tolerance should be within 0~+6dB.
In the semi/full microwave anechoic chamber, without EUT, and while turning on positioner, antenna tower, CCTV sensor and lamps, the test level of the space background noise should be at least 10dB lower than the limit level Class B stipulated in standard EN55022, GB9254-1998 under frequency of 30MHz~1GHz.
Besides the EMC anechoic chamber, we also provide the integration of EMC test system (including EMS test system and EMI test system). Application: The EMC test system apply in testing, evaluating electromagnetic compatibility to control quality armaments, defence goods and products in military.
