37、ION CABLES TEST METHODS Part 1-1: Electrical Measurement of the pulse/step return lossin the frequency domain using theInverse Discrete Fourier Transformation (IDFT)FOREWORD1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisingall national e

38、lectrotechnical committees (IEC National Committees). The object of IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, IEC publishes International Standards, Technical Specif

39、ications,Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IECPublication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interestedin the subject dealt with may participate in this preparatory work. Internationa

40、l, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closelywith the International Organization for Standardization (ISO) in accordance with conditions determined byagreement between the two organizations.2) The formal decisi

41、ons or agreements of IEC on technical matters express, as nearly as possible, an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees.3) IEC Publications have the form of recommendations for internatio

42、nal use and are accepted by IEC NationalCommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate, IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.4) In order to pr

43、omote international uniformity, IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications. Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indic

44、ated inthe latter.5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with an IEC Publication.6) All users should ensure that they have the latest edition of this publication.7) No liability shall attach to IE

45、C or its directors, employees, servants or agents including individual experts andmembers of its technical committees and IEC National Committees for any personal injury, property damage orother damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpen

46、ses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IECPublications.8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications isindispensable for the correct application of this publication.9) Attention

47、 is drawn to the possibility that some of the elements of this IEC Publication may be the subject ofpatent rights. IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 62153-1-1 has been prepared by subcommittee 46A: Coaxialcables, of IEC technic

48、al committee 46: Cables, wires, waveguides, r.f. connectors, r.f andmicrowave passive components and accessories.This standard cancels and replaces IEC/PAS 62260 published in 2001.
