CHC Plus

Pre-compliant 3m Compact EMC Chamber

The CHC Plus is Frankonia’s version of the compact hybrid chamber solution at 3,0m measuring distance with a Quiet Zone (QZ) of ø1,2m that meets the SVSWR verification. The CHC Plus 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 3,0m measuring distance.
