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 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 Chamber Filters
RF leakage through Ethernet and USB cables can destroy even the best RF enclosures and chambers. The need for filtering in the ever congested RF environment requires special filters that can pass USB 2.0 and 10/100/1000 Mbps Ethernet signals and filter out unwanted higher frequencies such as cellular and WiFi. The Adaura Technologies USB/Gigabit Filters provide one GigE and one USB 2.0 pass-through connections while filtering out other RF up to 8GHz. It has a small form factor to allow easy installation. It is a most cost effective solution for a clean chamber set up. In a typical chamber, WiFi signals are reduced to <-100dBm with this filter installed.

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.

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.

Electromagnetic anechoic box/Shield box/Anechoic chamber
The necessity of a wireless system test has risen by the spread of recent wireless telecommunication equipment as shown in cellular phone, wireless LAN, RF-ID tag and ETC (Electronic Toll Collection system). It is necessary for a wireless test to be performed in anechoic environment in which an external noise is intercepted and a radio wave does not reflect internally. An anechoic chamber (room version of a shield box) is proper facilities but needs a wide space and a huge cost. Especially, the equipment under wireless system test on the production line can not radiate any signal radio wave outside before approval. The shield box satisfies these conditions.
