23、TROTECHNICAL COMMISSION _ INTEGRATED CIRCUITS MEASUREMENT OF ELECTROMAGNETIC EMISSIONS Part 8: Measurement of radiated emissions IC stripline method FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnica
24、l committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Te
25、chnical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, govern
26、mental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions o
27、r agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for internationa
28、l use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to
29、promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly i
30、ndicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies
31、. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property d
32、amage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this p
33、ublication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or al
34、l such patent rights. International Standard IEC 61967-8 has been prepared by subcommittee 47A: Integrated circuits, of IEC technical committee 47: Semiconductor devices. The text of this standard is based on the following documents: FDIS Report on voting 47A/868/FDIS 47A/870/RVD Full information on
35、 the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 61967-8 IEC:2011 This part of IEC 61967 is to be read in conjunction with IEC 61967-1. A list of all
36、 parts of IEC 6xxxx series, under the general title Integrated circuits Measurement of electromagnetic emissions can be found on the IEC website. NOTE Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the t
37、ime of the next edition. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, with
38、drawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour print
39、er. 61967-8 IEC:2011 5 INTEGRATED CIRCUITS MEASUREMENT OF ELECTROMAGNETIC EMISSIONS Part 8: Measurement of radiated emissions IC stripline method 1 Scope The measurement procedure of this part of IEC 61967 defines a method for measuring the electromagnetic radiated emission from an integrated circui
40、t (IC) using an IC stripline in the frequency range of 150 kHz up to 3 GHz. The IC being evaluated is mounted on an EMC test board (PCB) between the active conductor and the ground plane of the IC stripline arrangement. 2 Normative references The following referenced documents are indispensable for
41、the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

47、purposes between the active conductor and the enlarged ground plane. As enlarged ground plane the ground plane of the standard EMC test board according to IEC 61967-1 should be used. An optional shielding enclosure may be used for fixing the IC stripline configuration and for shielding purposes. Thi
