3m CompliantSemi-Anechoic EMC Test Chamber


Designed for accuracy. The 3-meter complaint EMC test chamber (3m-SAC-C) is purposely designed for commercial EMC testing. Combining compliant emissions and immunity testing into one facility, the 3m-SAC-C provides the complete solution to ensuring your products meet both national and international standards for EMC compliance.
From the very start of product design to final compliance testing, having your own in house test facility becomes a fast, efficient and versatile way to demonstrate your products complies with applicable EMC standards and are compliant and ready to market.

Shaped Around Your Products


The 3m-SAC-C is designed and manufactured to meet the dimensions, weight and required test standards of your products. With an external height of 5.5 meters, the test chamber can perform sweeping height antenna measurements from 1.0 to 4.0 meters whilst seamlessly coordinating with the flush-mounted turntable installed in the test chamber.

The modular shielding system enables the test chamber to be designed for larger product ranges by increasing the dimensions in 100mm increments. A large range of high-performance accessories allows all services and penetrations to be integrated into the shield, without compromising the shielding performance.

All test chambers require a point of entry. The design and manufacture of the shielded door is critical to both ease of use and shield effectiveness. Each shielded door is handcrafted in Great Britain to the exact dimensions required. This ensures the equipment under test can be easily transported inside the test chamber regardless of weight or size. With a full range of ultra-low friction manual swing, pneumatic or sliding doors entering and exiting a test chamber has never been easier.

3m Pre-Compliant 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.

Semi-Anechoic


The walls and ceiling are lined with anechoic material to absorb reflections of electromagnetic waves inside the chamber. This creates a stable and repeatable environment to perform testing, mimicking and open area test site (OATS).

EMC


Electromagnetic compatibility or EMC testing gives the manufacturer of a product the ability to demonstrate the ability of their product. That it can function without causing interference to other devices (Emissions) and can also work satisfactorily in the proximity of other electrical and electronic devices (Immunity). The 3m-SAC-C can be used for both Immunity and Emission testing.

Test Facility


The external construction is an EMI/RFI shielded room, using a Faraday cage principle. This is to stop unwanted signals from the ambient environment entering the chamber and causing interference whilst tests are being performed. It also provides a safe and legal environment for immunity testing to take place. This means that, unlike Open Area Test Sites (OATS), the 3m-SAC-C can be installed in Urban and Industrial environments where high levels of RF interference are present.

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.
