CHC is the best solution for immunity tests according to the standard IEC / EN 61000-4-3 for a measurement over 3m, it offers the best performance for emission tests in pre-compliance. The installation of ferrites and hybrid absorbers on a part allows measurements on a frequency band of 30MHz to 18GHz. This chamber is also available with a ground plane (semi-anechoic) or with absorbents over the entire floor surface (completely anechoic). For immunity tests, the ground absorbers are needed between the transmitting antenna and the equipment under test, this is why they are included in the standard version.
