CHC Plus

Pre-compliant 3m Compact EMC Chamber






Test distance





CISPR 16-1-4


IEC/EN 61000-4-3




ø1,2 m


Pre-compliant EMI from 30 MHz to 1 GHz
Full compliant EMI from 1 GHz to 18 GHz
Full compliant EMS

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.


>     Full compliant EMS and pre-compliant EMI solution up to 1 GHz (NSA), full compliant above 1 GHz (SVSWR)

>     Cost effective solution for EMS and limited EMI measurements

>     Compact chamber design with advanced absorber lining with long-lasting Frankosorb® absorbers

        (Frankonia technology)

>     Turnkey solution
