It is well known that cable twisting is beneficial for reducing the low frequency emissions from, and coupling to cables. However, many misconceptions have evolved with respect to the actual contribution of the cable twisting at high frequencies, in particular with respect to the electric-field and electromagnetic field emission from and coupling to cables. In fact, in certain text books, the \"pair-balance\" is attributed to twisted pairs, contributing a rejection of 20 dB and more. In the present paper, the actual effect of cable twisting on the reduction of radiated emissions due to common-mode and differential-mode fed signals is presented and discussed. Tests were conducted by the authors, in order to investigate the effect of pair twisting on the interference coupling to cables. Due to the duality between emission from- and coupling to cables, the results obtained by means of measurement of the field emission from the cables for common-mode and differential mode feed to the culprit cable can be applied for the estimation of the effect of twisting on the coupling to the cables of the system. It is clearly shown that for high frequency common mode emissions, absolutely no reduction in radiated emissions may be expected due to the pair-twisting. Results are also compared to the those obtained by the shielding of cables, with the shield grounded at one and both sides.<<ETX>>","PeriodicalId":154914,"journal":{"name":"Proceedings of IEEE Symposium on Electromagnetic Compatibility","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124594230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two primary factors contributing these problems are available physical space and available electromagnetic spectrum. Due to the close proximity of platforms and equipment, close coordination is necessary for the effective and efficient utilization of the electromagnetic spectrum. While the US Navy was forced by necessity to deal with global spectrum management considerations, national and international implications of spectrum usage are becoming more prevalent in other governments around the world. As international travel and trade have grown and flourished, certain conventions or conferences evolved to cooperation for the mutual of all parties concerned. Cooperative use of the electromagnetic spectrum via the International telecommunications Union (ITU) is an example. The demands on spectrum usage are going to be much more dynamic, and require the participation and cooperation of all nations and all entities, departments, and agencies within these particular nations. Automated spectrum management systems will be required to handle the tasks of frequency allocation, frequency assignment, frequency allotment, etc., in a dynamic fashion to control and reduce electromagnetic interference. This paper presents the design considerations associated with one such system, the US Navy's Automated Spectrum Planning, Engineering Coordination and Tracking System (ASPECTS).<<ETX>>","PeriodicalId":154914,"journal":{"name":"Proceedings of IEEE Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130910903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
