It's all in Part 15, spread about. 47CFR15.27
47CFR15.31(j) -----Original Message----- From: Scott Douglas [mailto:[email protected]] Sent: Thursday, September 04, 2014 2:31 AM To: [email protected] Subject: [PSES] FCC EMI Test and Ferrites on Cables Fellow List persons... Please help refresh a tired brain. A designer of a product tells us that he passes FCC emissions testing if he puts ferrite sleeves (beads?) on the four HDMI cables connected at the rear panel of the product. He tells us that all he needs to do is add a statement in the user manual to the effect that the HDMI output cables must have ferrite sleeves (beads?) on them. He says he does not need to specify manufacturer name and part number of the ferrites. He says he does not need to provide the ferrites with the product. He also does not plan to include the HDMI output cables with the product because every installation will have different length HDMI cables needed. Now, my old brain thinks the above is not acceptable and that the FCC says that anything special needed to pass FCC testing must be provided with the product. And I am thinking that ferrites are special as you can't get them at Walmart or Radio Shack or Ace Hardware. And not all ferrites are the same. Can anyone confirm my memory and maybe give a pointer to the part of the FCC Rules that clarify this? Or have the rules changed over the years and I just missed that part? Thank you in advance for any and all comments, on list or off.
