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.
Shielding Effectiveness of Shielding Body
| 14KHz | magnetic field | ≥65dB |
| 100KHz | magnetic field | ≥90dB |
| 200KHz | magnetic field | ≥100dB |
| 15MHz | electric field | ≥100dB |
| 450MHz | plane wave | ≥100dB |
| 1GHz | plane wave | ≥100dB |

Performance of EMC ChamberNormalized 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.
EMC Test System Features:a) Meet the standard of MIL-STD-461F; accomplish 18 EMC test systems; b) Easy to operate with high automation; c) Test equipments meet the standards as CISPR16-1-1, and etc; d) Friendly software interface, can realize device control, parameter adjust, data read, auto-calibration and report functions.
With the strong support from No. * institute of CETC corporation.Lopu has developed and produced multitudinous microwave product, constructed more than 100 large microwaves anechoic chambers (which include the biggest three specialized anechoic chambers of China and the biggest antenna surveys anechoic chamber in Asia) and integrated more than 30 antenna far and near field measurement systems in the field of wireless communication, radar, aerospace and civil electronics for 20 years.
