5m Compliant Semi Anechoic Chamber

5m measuring distance for standard sized EUT’s or 3m measuring distance for larger EUT’s.


Global EMC’s SAC-5m-C is a semi anechoic 5m EMC compliant test facility. It is the perfect solution for users who want to measure at a test distance of 3m or 5m. The chamber is designed for both compliant emission and compliant immunity testing. The self-standing steel structure and modular steel shield enables a fast and efficient construction process. A combination of high performance GF 102 ferrite tiles and pyramidal Hybrid Absorbers are used to create optimum performance.


The chamber designed to bridge the gap between a compliant 3m measuring distance and a compliant 10m measuring distance chamber. This offers a cost effective solution as the chamber can be used for a variety of standards to give you a multi-functional solution to your testing requirements. This chamber can also be used as a 3m measurement distance chamber for larger EUT’s.
