3m Compliant Fully Anechoic EMC Test Chamber
Designed for speed. The 3m Compliant Fully Anechoic EMC Test Chamber (3m-FAC-C) is a shielded enclosure combined with the latest generation anechoic material installed on all walls, ceiling and floor. The key difference between a Semi anechoic test chamber 3m-SAC-C and a fully anechoic is the inclusion of the anechoic material to the majority of the floor area. This creates a test chamber without ground reflections and does not require a 1.0m to 4.0m antenna sweep during emissions testing. A fixed antenna height is used focused centrally on the test volume.
This gives two important advantages for this test chamber. It decreases the time required to perform radiated emissions testing and therefore improves efficiency and a higher throughput of products. Also, it allows the test chamber to have a lower ceiling height. This reduces the initial capital expenditure and the space required to install the test chamber in the host building.

Conforming to NSA and SVSWR validation criteria in accordance with CISPR 16-1-4, the 3m-FAC-C is the perfect solution to perform tests in accordance with a wide range of standards. Whether performing EMC Emissions and Immunity testing or Radio measurements the 3m Compliant Fully Anechoic EMC Test Chamber is a cost-effective and multi-functional solution to EMC testing requirements.
Compliant
Radiated Emission – Electro-Magnetic Interference (EMI) to CISPR 16-1-4 / EN55016-1-4.
Immunity
Compliant Radiated Immunity – Electro-Magnetic Susceptibility (EMS) to EN/IEC6100-4-3.
Components
Smaller table top products and EUT’s that do not require wheeled access into the test chamber.
Fully Anechoic
Fully anechoic test chamber with latest generation anechoic absorbers to all walls, ceiling and floor.
Test More, Wait Less
The versatility and testing speed of the 3m-FAC-C, fully anechoic test chamber is unmatched with other testing facilities.
Performing EMC Emissions and Immunity testing quickly and seamlessly in one test chamber with only a minimal reconfiguration between tests. This reduces delays, lead times and increase the throughput of products.
A combination of high-performance GF 102 ferrite tiles and latest generation pyramidal Absorbers are used to create optimum performance inside the chamber. The inclusion of absorbing material to the floor area mimics free-space conditions allowing a fixed antenna. The absorbers are easily repaired or replaced if accidentally damaged, using the fast and convenient “plug-in” base system.
The fully anechoic test chamber is fully configurable to your exact requirements but as standard comes in two dimensions. The 3m-FAC-C and the 3m-FAC-C-L for larger test items (EUT’s). Please see the specification below for further details.
3m Fully Anechoic EMC Test Facility
3m
A 3-meter test distance between the antenna and equipment under test is available in this test chamber.
This test distance is widely used and accepted around the world in a large range of regulatory or standard-based test configurations.
Fully Anechoic
Designed to CISPR 16-1-4 as a test chamber without ground plane under free-space conditions.
Anechoic absorbers are installed to all walls, ceiling and floor area. Leaving only a small walkway available on the floor for ease of access.
Test Facility
Having a maximum height of 4.4 meters, the test chamber has the ability to be installed in smaller host buildings where space is limited.
Performance and accuracy are maintained through careful design and high manufacturing standards.
High-Performance Anechoic Lining
Ferrite Tiles & Absorbers – The walls and ceiling of the test chamber are precisely lined with the latest generation gapless Hybrid Pyramid absorbers and Ferrite tiles. The Pyramidal absorbers are precisely doped to ensure a smooth transition between the high performance of the Ferrite tiles at lower frequencies to the Pyramidal absorbers in higher frequencies. The “plug-in” base system of the absorbers means that individual absorber cones can be replaced if accidentally damaged during operation of the test chamber. This reduces the cost of repairs and time taken for the test chamber to become fully operational again.

Shielding Effectiveness tested to EN 50147-1
Every Global EMC anechoic chamber is provided with a Faraday cage shield. The shielded enclosure provides both an area free from external ambient signals but also protection during Immunity testing for personnel working outside the chamber.
The measure of shielding performance is conventionally known as “shielding effectiveness”. 100dB in plane and microwave frequencies is generally regarded by most standards as a very high level of shielding suitable for scientific use.
Global EMC offer two levels of shielding Standard and Extended Performance. Standard performance is suitable for most shielding requirements and is typically seen in commercial testing situations. Extended Performance is usually used in high-performance Military applications along with certain high frequency needs.
Radiated immunity – Compliant to IEC/EN 61000-4-3 80 MHz – 6,000 MHz (18 GHz optional).
