10m Compliant Semi-Anechoic EMC Test Chamber

Size matters. Considered the Gold Standard in EMC emission measurement. The 10m Compliant Test Chambers have every aspect designed in the pursuit of performance.


The 10m Compliant Test Chambers are available in two variations, the 10m-SAC-LP and the 10m-SAC-FH. Commercial, automotive, military and Avionic test procedures can all be performed in this versatile and adaptable test chamber.


With 204m² of internal free floor space as standard. 10m Compliant Test Chambers are remarkably spacious and large enough to accommodate full vehicles and voluminous products for EMC testing. Heavy-duty flooring and large turntables enables the chamber to be suitable for the ruggedized and demanding requirements of military component and military vehicle testing. The increased size allows even large products to be measured in their far-field of emanations, providing a complete and comprehensive EMC test chamber solution.

Limitless Possibilities

Our 10m Compliant Test Chambers, with the 10m-SAC-LP and 10m-SAC-FH, an almost limitless number of possibilities are available. With a large and diverse selection of components and accessories, Global EMC can configure the test chamber to your exact needs.


Vehicle access to the test chamber is simplified with automated sliding doors and pneumatic ramps. Up to 16-meter diameter, turntables provide positioning systems for even the largest of vehicles.


Honeycomb vents work in conjunction with Air Conditioning (HVAC) or vehicle extract systems to quietly dissipate heat and fumes and control the internal temperatures of the test chamber.

A wide range of EMI filters are available, providing power and data into the room whilst maintaining >100 dBs of Insertion Loss.

Ultra-low emission LED lighting is provided to illuminate the test chamber whilst staying below the noise floor of even Military testing parameters. Shielded Control rooms and Amplifier rooms are configured to exact specification. Including options of air conditioning, fire detection, furniture and dimmable lighting makes the environment a comfortable and safe place to work.

10m Semi-Anechoic EMC Test Facility


A 10-meter test distance is required between your antenna and equipment under test. This separation distance gives the chamber its distinctive rectangular shape.


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).


A SAC 10m-C is a semi-anechoic chamber predominantly for EMC testing but can be used for other standards as well.

Test Facility

The external construction is a shielded room, using a Faraday cage principle. This is to stop unwanted signals from the external environment entering the chamber and causing interference whilst tests are being performed.

High-Performance Anechoic Lining

Ferrite Tiles & Absorbers – The latest generation Hybrid Pyramid Absorbers are installed to compliment ferrite tiles. This provides a broadband anechoic performance, whilst using as little of the internal space as possible.

Shielding Effectiveness tested to EN 50147-1

Our 10m Compliant Test Chambers, as with 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.
