Investigations on Repeatibility of Radiated Emissions Testing for Frequencies below 30 MHz

In this paper, some methods concerning improving repeatability of Radiated Emissions (RE) testing for frequencies below 30 MHz are proposed and investigated. The proposals are made in the context of the CISPR 25 Annex J standard and are devised for improving testing activity in the Automotive industry. A proposed solution is intended for reducing spurious signal coupling and resonances during tests in a semi-anechoic chamber. This work represents the continuation of a previous paper by the authors on the topic of Absorber Lined Shielded Enclosure (ALSE) Chamber Validation.
