MEASUREMENT TECHNIQUES

This series of documents is a non-exclusive list of measurement techniques that may be used when testing equipment to determine its compliance with FCC rules. This list is provided as a reference tool to aid interested parties in locating measurement techniques. Any party making measurements to show compliance with the FCC rules should select the appropriate measurement methods as required and specified in the particular part of the FCC rules. (For example, for Part 15 devices see §§15.31, 15.32, 15.33, and 15.35 of title 47 of the Code of Federal Regulations (C.F.R.)). The FCC Knowledge Database provides additional guidance on testing devices subject to the FCC's rules.
