EMC Chamber

Short Description

The CHC is the optimal solution for immunity tests according to the standard IEC/EN 61000-4-3 for a measuring distance of 3.0 m and offers in this size the best characteristics for pre-acceptance emission measurements. The installation of ferrite and partially of hybrid absorbers allows measurements in the frequency range from 30 MHz to at least 18 GHz. The CHC can be delivered optionally as a semi-anechoic chamber (with ground plane) or as a fully anechoic chamber (floor absorbers on the whole floor surface). For immunity tests, floor absorbers are required in each case between transmitting antenna and EUT and are therefore included in the standard delivery volume. 

Short Description

The ACTC was developed especially for radiation testing of automotive components according to the standard DIN/ISO 11452-2 and EN 55025 (CISPR 25) and adjusted in all details to this objective. The chamber is lined with ferrite absorbers and approximately up to the middle of the chamber with additional hybrid absorbers. In the standard version the floor of the chamber consists of a normal false floor. As an option this version can be delivered with an additional ground plane or with floor absorbers. The standard version of the ACTC is qualified for measurements in the frequency range from 30 MHz to at least 18 GHz. A (plug-in) contact-strip, to be permanently installed between the absorbers for assuring the electric contact of the ground plane of the testing table to the shielding panels, is available as standard as well as the 
testing table itself.

Short Description

The AVTC is a standard chamber for radiated emission and immunity testing on vehicles and components acc. to CISPR

12 / 25 and ISO 11451-2 / ISO 11452-2.

 

The standard dimensions of the chamber allow vehicle testing up to a length of 5.5 m (on turntable) and a measuring distance of 3.0 m. With additional (optional available) floor absorbers it is simply possible to upgrade the chamber for emission measurements acc. To EN 55022 (CISPR 16-1-4) and immunity tests acc. to IEC/EN 61000-4-3.

Short Description

The MIL-CHC has been designed to fulfill the requirements for radiated emission and immunity testing acc. to MIL-STD 461E. The below specified standard dimensions of the chamber are suitable for a width of the testing table up to 3.0 m. Bigger dimensions are available on request. The standard version does already include the contact strip for the ground-plane of the testing table as well as the testing table itself. Contact strip Test table

Short Description

The SAC-3 / -5 Plus is a full-compliant semi anechoic chamber for a measuring
distance of 3 or 5 meters. It´s dome shaped roof as well as it´s optimized absorber layout, with ferrite and partial hybrid absorber lining for the frequency range from 26 MHz to 18 GHz, leads to minimized reflections. Due to the relative short hybrid absorbers, the chamber can be smaller in its dimensions than a chamber lined with long pyramid absorbers. The SAC-3 / -5 Plus delivers outstanding performances for both, NSA (±3.5 dB) from 30 MHz to 1 GHz, and SVSWR (5 dB) from 1 GHz to 18 GHz conforming to the site validation standard CISPR 16-1-4 for SVSWR. The standard version does already include the antenna mast for 1-4 m height scan, the turntable as well as their controller.

Short Description

Anechoic chambers for 10.0 m measuring distance are planned and realized almost exclusively at customers´ requirements. However, for a first impression about size and performance of a SAC-10 we defined below 4 standard model with quiet zone diameter from 2.0 m to 5.0 m. The planning of an anechoic chamber should be made as early as possible, i.e. together with the planning of the building itself so that the interfaces can be defined in time which will avoid later modifications. Typical interfaces  are as follows: any kind of supply media, spaces reserved in the concrete floor for turntables / rolling test stands or driving pits for sliding gates, as well as a possible fastening of the room construction to the building construction. Furthermore, possible interfaces to emergency control / alarm systems, for example fire alarm and fire extinguishing systems, have to be considered, too. Such systems are normally not required when using our non-combustible pyramid absorbers in “thin-film” technology (fire class A2).
