Hi All, Do not see and mode-mixers in that EMC testing room. The vehicle EMC testing rooms I have been had big tin-foil fans that rotate. They vary any resonances in the room to randomly get the peak amplitudes in all parts of the room.
I haven't had time to watch the webinar yet, but interestingly, last night, on the news, I saw a clips of a video supposedly recently released by Toyota of their test chambers. The clips they showed looked like the last video of the webinar. Notice Toyota releases video of testing chamber and Toyota releases video of testing chamber at Boston.com are dated 3/22/10. edit: This looks like the news story I saw that night http://edition.cnn.com/video/#/video/us/2010/03/22/feyerick.toyota.electronics.cnn?iref=24hours.
