EMC Anechoic Chambers

1. Semi Anechoic Chamber (SAC)

Semi Anechoic Chambers has five anechoic surfaces and one ground surface. That’s thy it is called semi-anechoic. We are offering semi anechoic EMC Chamber up to 30 meter test distance for full compliance EMC emission and immunity testing. These chambers are used for EMC testing for commercial, medical, automotive, avionics and education fields. SACs have better performance for NSA, sVSWR and Field Uniformity. Some CISPR standards requires a semi anechoic chamber with 9x6x6m dimensions. Other CISPR standards has some requirements depending on the EUT size and dimensions.  

2. Fully Anechoic Chamber (FAC)

Fully Anechoic Chambers have six anechoic surfaces and no ground or reflective surface. That’s why it is called fully-anechoic. Fully anechoic chambers are used in both EMC and antenna chambers for test application which requires fully lined RF absorbing materials on the ground and all inner walls. Pyramidal RF absorbers are required for the frequencies over 1 GHz. Fully Anechoic Chamber (FAC) might include these options: control/shielded room, turn-table, antenna mast / tripod, antennas, RF cables, audio/video system to monitor inside the chamber, lighting system, ventilation system, fire system, non-conductive test table, measurement systems (RF signal generator, RF amplifier, electric field probe, test software, EMI receiver and etc.) 

3. Antenna Anechoic Chamber

RF Microwave Absorber Pyramidal foam cones or High performance Polypropylene Hybrid material are used in antenna chambers. Antenna chambers are used for performance tests of antennas. These chambers are mostly used by antenna designers, manufacturers, researchers and universities.

We are offering turnkey solutions for Antenna Measurement Systems, RF Shield room, Anechoic Chamber and RF Absorber. 

4. RTCA DO-160 Anechoic Chamber for Civil Avionics

Products used in avionics are tested according to RTCA DO-160.  We are offering anechoic chambers comply with latest version of the standard: RTCA DO-160G.

5. CISPR 25 Anechoic Chamber for Automotive

Electronic products used in automotive industry and vehicles are tested according to CISPR 25. It is also referred by UN ECE Regulation 10 and ISO 11452-2 standards. CISPR 25 chamber is a RF-shielded semi-anechoic chamber providing an ideal environment for compliant CISPR 25 testing. CISPR 25 Anechoic Chambers are also under the scope of manufacturers standards like Ford’s FMC 1278 and FMC 1280. Learn more about CISPR 25 Anechoic Chambers.

6. CISPR 12 Anechoic Chamber for Automotive

Emissions of vehicles are tested according to CISPR 12. CISPR 12 requires test environment OTS or ALSE (anechoic chamber)

7. ISO 11452-2 Anechoic Chamber for Automotive

Radiated Immunity tests of vehicles are tested according to ISO 11452-2. ISO 11452-2 standard requires test environment to be open test site or Absorber Lined Shielded Enclosure (anechoic chamber). ISO 11542-2 Anechoic Chambers are also under the scope of manufacturers standards like Ford’s FMC 1278 and FMC 1280. 

We are offering screened or shielded rooms which are screening RF signals for these purposes:

1. Control Rooms (of anechoic chambers),
2. Amplifier Rooms (of anechoic chambers),
3. RF-isolated meeting rooms,
4. Medical EEG (ElectroEncephaloGram) Rooms,
5. MRI (Magnetic Resonance Imaging) Rooms,
6. High Voltage Test Laboratories.

You can perform any EMC test inside an EMC anechoic chamber since the chamber provides you an RF isolated environment. However, EMC Anechoic Chambers are mostly used for radiated tests: emissions and immunity. 

1. Emissions

Emissions radiated from the tested product is measured inside the EMC test chamber. In order to perform these tests you also need emissions test system. For Radiated Emissions tests, test system consists of Antenna, RF Cable and Connectors, EMI Receiver and Test Software.

2. Immunity

During immunity tests, tested product is subjected to disturbing electromagnetic signals. For radiated immunity tests, the product is subjected to a uniform electric field. To create a uniform electric field, you need anechoic chamber. In order to perform these tests you also need immunity test system. For Radiated Immunity tests, test system simply consists of Antenna, RF Cable and Connectors, RF Power Amplifier, RF Signal Generator and Test Software.
