Reverberation Chambers
Over the past several decades, RCs have been enjoying growing popularity as a promising facility for the characterization of wireless devices and for EMC testing. The RC (Reverberation Chamber) measurement method exhibits much competitive superiority over the AC (Anechoic Chamber) method and TEM Cell method, such as low cost, enhanced test repeatability, a more realistic test environment, and easily achieved high-field environment. The application of the RC for performing EMC testing was first proposed by H. A. Mendes in 1968. In the recent IEC 61000-4-21 standard, the importance of EMC testing using RCs as an alternative measurement technique has been recognized.

Large-size Hybrid Reverberation / Anechoic Chamber
F-Series
The F large-size hybrid Reverberation/Anechoic Chamber represents the most versatile OTA test system in the market today. With the same unique test features of their E Series RC counterparts, the F-Series can also test large form-factor devices under test (DUTs) like laptops, large TV sets, solar and trash compactors, drones, fridges or washing and vending machines, among others. With up to 16x16, 8DLCC and DUTs up to 2m and 500 kg including full-body phantoms in a turntable, the F Series also expands the frequency range down to cover 200 MHz up to 40 GHz frequency ranges and the test modes to include EMC, BS, small cell, eNodeB and Virtual Drive Testing over the air (VDT-OTA). In an again unheard-of feature, the F-Series is also reverse-convertible into an Anechoic chamber, allowing Far Field (FF) and Spherical Near Field (SNF) radiation patterns, efficiency and gain measurements and pre-5G testing of antennas and devices. Conversion from RC to AC or vice versa can be performed within half a day.

Anechoic Chamber
Wedge:The acoustic absorptivity of sound-absorbing materials used in anechoic chamber must be greater than 0.99. In anechoic chamber, gradient absorption layer, wedge or conical structure are often applied with glass wool and flexible foam as its sound-absorging materials. Anechoic Door: The design of rotatable door can affect the whole function of anechoic chamber. Therefore, it's crucial to combine steel plate and sound-absorbing cotton in the door, which is exactly our design.Acoustic Insulating Material:Applying high-density materials to enclose external noise. Damping materials: Using spring, rubber and cotton to enhance damping capacity.The Anechoic Chamber conforms to GB/T 6882-86 and ISO 3745 specifications.

Anechoic chambers
The anechoic chambers are built up as a modular construction. Due to individual modules any size of chamber can be manufactured. Big chambers may require an outer supporting structure or alternatively the shielding material can be attached direct to the building. The absorbers are fixed to rails bars or wooden base construction which is inserted into the shielding modules.

Anechoic Chambers
Eckel Noise Control Technologies
Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements or SuperSoft panels, depending on performance level required and cut-off desired.
