This third and final part looks at Section 6 (Interference Potential of EDP/OE), Section 7 (The Commercial EDP/OE Interference Models), Section 8 (Emanation Limits for EDP/OE Products), Section 9 (Comparisons of Recommended Limits with Others), Section 10 (Emanation Measurement), and Section 11 (Conclusions).

The first part of this paper reviewed the first one-third of the report including the Title of the Paper, the Background to its development, the Members of the Subcommittee that developed the report, Definitions, Table of Contents, Scope and Section 4. This second part of the paper will look at Section 5 (Susceptibility of Communications Receivers to Commercial EDP/OE Emanations) of the Report.

In the middle of the 1970s, the United States Federal Communications Commission (FCC) began to look seriously at electromagnetic emissions from electronic data processing (EDP) equipment and office equipment (OE). This growing awareness on the part of the United States telecommunications regulation body was a result of the increasing number of computers being used by society and the increased potential for growth by licensed broadcast services due to the proliferation of electronic-computer sources. The Computer and Business Equipment Manufacturers Association (CBEMA) formed a technical subcommittee to assist in preparing an industry response to the concerns of the FCC. This paper reviews the report developed by that technical subcommittee, made public in May of 1977.
