Its development took about one year. At the beginning of 2008, a prototype was validated by an independent laboratory according to all the standards for anechoic chambers.

The SAC3+™ is a full-compliance anechoic chamber for a measuring distance of 3m
(1-4m height scan) and for a test volume of 2.0m diameter and 2.0m height, and that in the complete frequency range from 26MHz to 18GHz.

In addition to its exceptional dome design and its optimized absorbers layout, this chamber delivers outstanding performances above the required minimum.

End of 2009, Frankonia sold 10 units SAC3+™ in Europe and Asia.
