That reminds me of a set-top b-b receiver I was testing long ago. While it met all the class B specs both rad and susc., when placed on top of a TV there were interference issues because of the close proximity! (both from the TV and from the set-top!) Depending on your application, you may

Hypothetical: Should a receiver mounted on an antenna be lit up during an emissions test? The receiver down-converts the received signal?? Sure. It has oscillators whose emissions might cause interference. Even if not required by law (Part 15 and receiver above 960 MHz not a radar detector) it's

. 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. -- From: Grasso, Charles charles.gra...@echostar.com To: emc-p...@majordomo.ieee.org Subject: Question on Receiver EMI testing
