I'm not going to claim to be an expert on this one, but this is my two cent's worth. From the point of view of what rf might leak from the EUT, it seems that an LO or IF would be the main concerns. I don't see how the absence/presence of a receivable signal would affect LO emissions. The amplitude of the IF signal would be proportional to received signal strength, so if the IF were in the band controlled by your emissions limit, that might be important.

List-Post: emc-pstc@listserv.ieee.org Date: Tue, Oct 29, 2002, 5:47 PM Group, A hypothetical question for you... Should a receiver mounted on an antenna be "lit up" during an emissions test? The receiver down-converts the received signal?? Thanking you all in advance.. Best Regards Charles Grasso Senior Compliance Engineer Echostar Communications Corp.
