A US only digital device product desires to incorporate various FCC Certified modules that can all transmit simultaneously. All modules are certified as single modular with grant notes stating "no co-location". All modules will be used in accordance with their grant notes except for co-location to other transmitters. What FCC Authorization method should be used for the product, SDoC or Certification?
Is co-location testing of the host the same as FCC 15B testing of the digital device? If during co-location testing there are signals related to the product digital device portion and not any transmitter (as verified by turning all radios off and disabling their communication path) what limit shall apply? Transmitter spurious limits (say the least/most restrictive) or general 15B limits (A/B depending on product type)?

If the individual devices in a composite system are subject to different technical standards, each such device must comply with its specific standards. In no event may the measured emissions of the composite system exceed the highest level permitted for an individual component. Testing for compliance with the different standards shall be performed with all of the devices in the system functioning. If the composite system incorporates more than one antenna or other radiating source and these radiating sources are designed to emit at the same time, measurements of conducted and radiated emissions shall be performed with all radiating sources that are to be employed emitting. So a part 15 device needs to comply with part 15, and a part 22 device with part 22, etc. I interpret the clause that I underlined as saying that an intermodulation product, it would "only" need to comply with the more relaxed limit of the two rule parts for the two transmitters that created it. Now, the engineer in me says that you should fix your design if you're creating intermodulation products, but I'm not sure this is address specifically in any rule or KDB Consideration of simultaneous transmissions for SAR are separate and covered under SAR KDBs Charlie Charlie Blackham Sulis Consultants Ltd Tel: +44 (0)7946 624317 Web: www.sulisconsultants.com<https://outlook.hslive.net/owa/redir.aspx?C=02be3bf3e3a544d1bdf7b6c99fbd12f5&URL=http%3a%2f%2fwww.sulisconsultants.com%2f> Registered in England and Wales, number 05466247 From: Grasso, Charles <charles.gra...@dish.com<mailto:charles.gra...@dish.com>> Sent: 27 November 2018 19:14 To: EMC-PSTC@LISTSERV.IEEE.ORG<mailto:EMC-PSTC@LISTSERV.IEEE.ORG> Subject: [PSES] Antenna Colocation test Hi - For an FCC product with multiple xmtrs a colocation test is required (<20cms).
