10m Champer

I What is the Champer ?

Electromagnetic compatibility (EMC) or anechoic chamber is a highly specialized test equipment used to test electronic devices to regulatory standards relating to both immunity and emission. radiated and conducted radio frequency (RF) radiation.

An EMC interference chamber or anti-echo chamber is designed to provide an enclosure with an extremely high level of shielding attenuation against electromagnetic interference.

The word ‘echoless’ simply means ‘without echo’. An anechoic chamber is a box, chamber or room designed to completely absorb the reflection of sound or electromagnetic waves.

The main feature of an anechoic chamber is that it is designed to absorb the reflection of waves inside the chamber instead of letting them bounce off the walls, which could cause an echo. If designed and assembled correctly, these chambers also do a great job of preventing waves from entering the chamber, especially as they provide shielding from outside interference. This combination means that the person or detector only hears direct sound, with no echoes, in effect simulating being in an extremely large room.

If you’ve ever shouted ‘echo!’ in a large room, you’ve probably noticed some kind of echo and you’ve heard your voice repeat a few times. To prevent this phenomenon, the anechoic chambers are lined inside with a material designed to completely absorb all sound waves, thereby eliminating any reflections.

II Fields that need to use champer rooms

In today’s industries, anti-echo chambers are used to perform EMC measurements according to many published EMC standards. There are many different application fields, including consumer electronics, automotive, aerospace, military, medical, telecommunications, research & development and others. Different organizations around the world develop and publish standards, resulting in different requirements and therefore different types of chambers.

III Champer application

The primary application of an anti-echo chamber is to determine whether a product or device complies with emission and immunity limits defined in specific industry standards. However, depending on your industry, anechoic chambers can be used for testing to a variety of EMC standards such as CISPR, IEC/EN, MIL-STD 461, and RTCA DO-160.

IV champer type

There are many types of anti-echo chambers designed for different types of applications. Some of the most common uses and types are for things like recording, radiated emission testing, radiation immunity testing, wireless transmitter (RF) testing, antenna testing and specific absorption rate (SAR) test.

EMC anechoic chambers, mainly those with conductive floors known as semi-anechoic chambers or SACs, are essentially used for radiated emission (RE) testing in the frequency range of 30 to 1000 MHz and Radiated immunity (RI) from 26 or 80 MHz to 1000 MHz, with extensions to 6 GHz, 18 GHz or even 40 GHz with RE measurements becoming more frequent.
