Ambient Noise is an extremely important parameter while validation of an EMC chamber. The Ambient noise measurement is carried out based on standards CISPR32/CISPR12, MIL STD 461 E/F/G between 150KHz-18GHz using a FPH Rider Spectrum Analyser connected to calibrated Monopole, Bi-conical and Horn Antenna (150KHz-18GHz).
The spectrum analyser is operated with settings recommended in Mil 461 F and limit lines loaded based on the requirement of the customer.
