Reverberation chambers (RVC) are modern EMC test environments that provide an alternative to semi or full anechoic rooms (SAR/FAR), open area test sites (OATS) or Gigahertz Transverse Electromagnetic (GTEM) cells. The new RVC XS and 2XS models expand Teseq’s extensive chamber portfolio.
RVCs consist of a shielded room and a ‘stirrer,’ which changes the resonant electromagnetic field distribution inside the chamber, producing a statistically uniform field. The two new RVC models are designed specifically to accommodate small Equipment Under Test (EUT), eliminating the need for a larger, more expensive, traditional chamber. Both models are fully assembled and tested in the factory and no on-site assembly is required as the chambers are delivered ready to use.
The 2XS, the smaller of the two chambers, has an internal size of 1.5 × 0.8 × 1.0 m, providing a test volume of 0.5 × 0.3 × 0.5 m at a start frequency of about 800 MHz. The larger model, the XS, has an internal size of 2.7 × 1.5 × 1.3 m, resulting in a test volume of 1.2 × 1.0 × 0.8 m and a start frequency of about 500 MHz.
Optimal mechanical stability of the two RVCs is achieved using a rigid construction and an outside reinforced frame. Furthermore, the inside of the chamber has a completely flat surface (no connective elements are used for pan type or sandwich construction), which is made of aluminium for optimal power and field performance. Field strengths of more than 100 V/m are easy to achieve with 1 W applied to the antenna and with an empty chamber.
Both chambers are fully equipped with a stirrer — designed and optimized for the intended frequency range in accordance with the requirements of the basic standards. The stirrer commands are provided in the user manual and enable easy implementation of the stirrer controller within any measurement software. Drivers and RVC application packages for Teseq’s Compliance 5 EMC software are available.
