EMC automotive testing is evolving and moving towards the Reverberation Chamber (RC) method, a trend that is accelerating now the new ISO 11541-5 standard for a full vehicle evaluation has been published. This presentation will begin by outlining the latest updates of the new ISO 11451-5, as well as highlighting the basic steps required to enable full vehicle testing in a reverberation chamber. The newly introduced closed-loop power control technique (fast-stirring) is of special interest and will be analyzed. Finally, a chamber design fulfilling the requirements of this new test technique backed by experimental data will be presented.
