Application:
Simulating open field test conditions, primarily for radiated interference (EMI) and radiation sensitivity (EMS) measurements.
Test Principle:
Also named EMC darkroom, belonging to the semi-anechoic darkroom (Semi-Anechoic chamber, referred to as SAC), an simulation open field mainly in the static zone, shielding effectiveness, normalized site attenuation, field uniformity, site voltage standing wave ratio and other parameters performance.
Structure:
The EMC darkroom generally consists of the main steel structure, shielding body, wave filter, air conditioning ventilated waveguides (divided into the wind inlet and outlet waveguides), shielding door, absorbing materials, lightings, interface boards, elevated floor, turntable, antenna tower, controller, monitoring systems, smoke alarm systems, and power distribution systems.
Different Anechoic Chambers:
| 1m Auto Parts Anechoic Chamber | |
| Overview | Automotive darkrooms are specifically designed for radiation
emission and radiated immunity tests of automotive components and
meet the requirements of DIN / ISO 11452-2 and EN 55025 (CISPR 25). Inside the darkroom, a ferrite absorbing material is installed, and a composite absorbing material is installed at a height of approximately the center of the darkroom. The standard test frequency range is at least between 30MHz and 18GHz. To ensure electrical connection between the ground plane of the test table and the shield, some conductive tape with beryllium copper spring was installed between the absorbing materials. |

| 3M Compact Anechoic Chamber | |
| Overview | 3m compact anechoic chamber to ensure that the test under the premise of 3m, reducing the darkroom appearance size, compact dimensions, powerful test capabilities, making it more suitable for general office and research facilities. Mainly used for RF immunity, emission estimation and free-space launch test, the test frequency range can cover 30MHz ~ 18GHz. In the frequency range of 30 MHz to 18 GHz, a vertical plane of 1.5 m × 1.5 m is defined in the EUT region, and the center height is 1.55 m, and the uniformity of field strength on the plane is required to reach that the maximum field strength deviation of at least 12 points among 16 points is within 0-6.0 dB. |

| Standard 5m Anechoic Chamber | |
| Overview | In the 5-meter method, the distance between the antenna and the walls of the darkroom is larger than the 3-meter method, making it easier to normalize the attenuation of the site. All of the above 60 MHz tests in the 5 meter anechoic chamber are far field tests. In open field tests, there are many signals propagating in the electromagnetic environment in the range of 60MHz to 100MHz, which make the 5-meter anechoic chamber have more prominent advantages than the 3-meter method open field and compared with the 10m method 3-meter law on the 10-meter conversion of the correction is more superior. You can test a larger volume of EUT. |
