Compact Fully Anechoic 3m EMC Chamber for table-top EUT’s

The FAC-3 is Frankonia’s fully anechoic chamber solution at 3,0 m measuring distance on table top positioned EUT’s. It is designed as full compliant chamber for measurements under free-space conditions and is based on CISPR 16-1-4 as a test site without ground plane. Without the reflections from the floor, a height scan is no longer necessary. With its specific requirements for the test site, Frankonia’s FAC-3 is supremely prepared to meet our customers’ demands.
