This Product Features

A low height of the chamber meaning it will easily fit within most buildings. The chamber is constructed using a self-standing steel structure and modular steel shield. This is complemented with high-performance pyramidal Hybrid Absorbers and ferrite tiles to walls and ceiling as required to make a semi-anechoic chamber.


Choose this testing facility for performing compliant radiated emissions with EN55025/CISPR 25 component and immunity testing to ISO 11452-2 component. This chamber is used for testing electronic sub-assemblies of receivers mounted on-board vehicles.

CISPR Automotive Component EMC Test Facility


CISPR 25:2016 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2 500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers and devices.

Automotive Component

Any component within a product or mechanism that comprises of a moving part engine, specifically for the testing and analysis of onboard receivers for vehicles.


Electromagnetic compatibility or EMC testing gives the manufacturer of a product the ability to demonstrate the ability of their product. A semi-anechoic chamber predominantly for EMC testing, as well as other standards.

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

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.
