Keyword: Part 15 Intentional and Unintentional Radiator measurement procedures

First Category: Equipment Authorization Process *
Second Category: General [Equipment Authorization Process]

Question:   What measurement procedures should be used for Part 15 intentional and unintentional radiators compliance testing?


Section 15.31(a) specifies the measurement procedures that are to be used for compliance testing* of Part 15 intentional and unintentional radiators as follows:

- MP-2: Measurement of UHF Noise Figures of TV Receivers.

- ANSI C63.4-2014: Unintentional Radiators (excluding subclauses 4.5.3, 4.6, 6.2.13, 8.2.2, and clauses 9 and 13);

- ANSI C63.17-2013: Unlicensed Personal Communications Service (UPCS) Devices; and

- ANSI C63.10-2013: Intentional Radiators.

The Equipment Authorization Report and Order (FCC 14-208) updated references to the measurement procedures for unintentional radiators (ANSI C63.4-2014) and intentional radiators (ANSI C63.10-2013). A one-year transition period was provided in the rules, which required that these standards be used by July 13, 2016. Devices tested using the previous editions of the measurement standards and authorized prior to the end of the transition period are not required to be re-tested using the editions of the measurement standards established by FCC 14-208.

Other key basic KDB publications pertaining to compliance testing of Part 15 intentional and unintentional radiators include: KDB Publication 414788 on test sites used for radiated emission measurements; KDB Publication 746324 concerning use of CISPR 22:1997 radiated emission limits for test data obtained using the required ANSI C63.4-2014 measurement procedures; KDB Publication 822428 on calibrations of antennas used for performing radiated emission measurements and test site validations; and, KDB Publications 789033 and 905462 with guidance for U-NII devices

In addition to the measurement procedures listed above, other measurement procedures that have been found to be acceptable for performing compliance measurements are listed on the OET equipment authorization measurement procedures page at: (https://www.fcc.gov/general/equipment-authorization-measurement-procedures).

The FCC Knowledge Database (https://www.fcc.gov/labhelp), and its Major Guidance Publications section (https://apps.fcc.gov/oetcf/kdb/reports/GuidedPublicationList.cfm), contains additional guidance on testing various devices subject to the FCC's rules.

* Other rules pertinent to compliance testing basic requirements include Sections 15.101, 15.201, 15.31(b)-(q), 15.33, 15.35, 15.37, 15.38, 15.215, 2.1033(b)(6), 2.911(c), 2.1075, and 2.955.
