Pre-compliant 3m Compact EMC Chamber

The CHC is Frankonia’s compact hybrid chamber solution at 3,0 m measuring distance with a Quiet Zone (QZ) of ø1,2 m. The CHC is an upgradable solution and can transform from a semi anechoic chamber configuration with ground plane to a fully anechoic chamber configuration with floor absorbers. It is an optimal solution for both pre-compliance emission tests and full compliance immunity tests at 3,0 m measuring distance.

The extended version of the CHC, called CHC-L, includes an absorber-lined partition wall that offers the feature for housing and storing RF power amplifiers, antennas, and floor absorbers inside the chamber.
