F-Series -
Emite Ingeniería SL. Ed
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.

MICRONIX
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.

MDC Vacuum Products llc
MDC stainless steel bell jars are designed for use with MDC baseplates, base wells and feedthrough collars. A dovetail groove in the jar's base flange holds a Viton elastomer gasket, which makes the vacuum seal with one of the forementioned components. All stainless steel bell jars are fitted with a four inch view diameter Pyrex viewport. All vacuum welds are internal and provide UHV compatibility. For added convenience, all bell jars are fitted with a hoist or lift-ring that is welded to the chamber's domed top.
