Specification for radio disturbance and immunity measuring apparatus and methods - Part 3: CISPR technical reports
CISPR/TR 16-3:2010(E) is a collection of technical reports that serve as background and supporting information for the various other standards and technical reports in CISPR 16 series. In addition, background information is provided on the history of CISPR, as well as a historical reference on the measurement of interference power from household and similar appliances in the VHF range. Over the years, CISPR prepared a number of recommendations and reports that have significant technical merit but were not generally available. Reports and recommendations were for some time published in CISPR 7 and CISPR 8. At its meeting in Campinas, Brazil, in 1988, CISPR subcommittee A agreed on the table of contents of Part 3, and to publish the reports for posterity by giving the reports a permanent place in Part 3. With the reorganization of CISPR 16 in 2003, the significance of CISPR limits material was moved to CISPR 16-4-3, whereas recommendations on statistics of disturbance complaints and on the report on the determination of limits were moved to CISPR 16 4-4. The contents of Amendment 1 (2002) of CISPR 16-3 were moved to CISPR 16-4-1. This third edition of CISPR 16-3 cancels and replaces the second edition published in 2003, and its Amendments 1 (2005) and 2 (2006). It is a technical revision. The main technical change with respect to the previous edition consist of the addition of a new clause to provide background information on FFT instrumentation.
