SAC-3 is a semi-anechoic chamber designed according to 3m test distance, which is mainly composed of the main anechoic chamber, control room and power amplifier room (conduction test room can be selected) for radiation immunity test and radiation emission compliance test at 3m distance. 3m method anechoic chamber is the most popular standard test environment, the static area can reach 2m diameter, widely used in IT products, household appliances, medical devices, automotive vehicles and parts, large military electronic systems, industrial electronic systems, communication fields and other electromagnetic compatibility testing.

◆ Main performance

1, radiation immunity test: meet the requirements of IEC/EN61000-4-3, IS011452 and other standards.

2, radiation emission test: in line with EN50022, EN50147-2, GJB151A and GJB152A standard requirements.

3, static area size: 2 meters diameter and 2 meters height of the cylinder (or customize other sizes of static area as required).

4, shielding efficiency: meet the standard EN50147-1, GJB12190 or better.

5, normalized site attenuation (NSA) : within 30MHz-1GHz according to CISPR16-1-4 and ANSIC63.4 standards meet ±4dB, 3.5dB, ±3dB, etc.

6, field strength uniformity (FU) : measured according to the requirements of IEC61000-4-3, within 0~6dB.

7, the site voltage standing wave ratio (SVSWR) in the range of 1GHz-18GHz according to CISPR16-1-4 standard is not more than 6dB.

8. Ambient Background Noise (ABN) : 10dB lower than the limit specified in the CISPR22 standard.
