20、ted emissions Surface scan method FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions

21、 concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”)

22、. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collabora

23、tes closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on th

24、e relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure tha

25、t 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the m

26、aximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodi

27、es 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. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to

28、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 damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

29、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 publication. Use of the referenced publications is indispensable for the correct application of this publication. 9)

30、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 all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptiona

31、l circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason,

32、 there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 61967-3, which is a technical specification, ha

33、s been prepared by subcommittee 47A: Integrated circuits, of IEC technical committee 47: Semiconductor devices. PD IEC/TS 61967-3:2014 IEC TS 61967-3:2014 IEC 2014 This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. This editio

34、n includes the following significant technical changes with respect to the previous edition: a) Removal of: 9.4 Data analysis; Annex D Analysing the data from near-field surface scanning. b) Addition of: Introduction 9.4 Measurement data 9.5 Post-processing 9.6 Data exchange Annex D Coordinate syste

35、ms c) Expansion of: 8.4 Test technique Annex A Calibration of near-field probes The text of this technical specification is based on the following documents: Enquiry draft Report on voting 47A/925/DTS 47A/937/RVC Full information on the voting for the approval of this technical specification can be

36、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. A list of all parts in the IEC 61967 series, published under the general title Integrated circuits Measurement of electromagnetic emissions, can be found o

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 transformed into an Int

38、ernational standard, reconfirmed, withdrawn, replaced by a revised edition, or amended.

PD IEC/TS 61967-3:2014 IEC TS 61967-3:2014 IEC 2014 INTRODUCTION Techniques for scanning near-fields radiated by integrated circuits and their surrounding environment can identify the areas of radiation, which may cause interference to nearby devices. The ab

40、ility to associate magnetic or electric field strengths with a particular location on a device can provide valuable information for improvement of an IC both in terms of functionality and EMC performance. Near-field scan techniques have considerably evolved over recent years. The improved sensitivit

41、y, bandwidth and spatial resolution of the probes offer analysis of integrated circuits operating into the gigahertz range. The ability to measure radiation both in the frequency and time domain allows not only analysis of fields generated by an IC, but also fields generated by externally applied di

42、sturbances propagating through the device. Post-processing can considerably enhance the resolution of a near-field scan measurement and the measured data can be shown in various ways, per users choice.

43、ETIC EMISSIONS Part 3: Measurement of radiated emissions Surface scan method 1 Scope This part of IEC 61967 provides a test procedure which defines an evaluation method for the near electric, magnetic or electromagnetic field components at or near the surface of an integrated circuit (IC). This diag

44、nostic procedure is intended for IC architectural analysis such as floor planning and power distribution optimization. This test procedure is applicable to measurements on an IC mounted on any circuit board that is accessible to the scanning probe. In some cases it is useful to scan not only the IC

45、but also its environment. For comparison of surface scan emissions between different ICs, the standardized test board defined in IEC 61967-1 should be used. This measurement method provides a mapping of the electric or magnetic near-field emissions over the IC. The resolution of the measurement is d

46、etermined by the capability of the measurement probe and the precision of the probe-positioning system. This method is intended for use up to 6 GHz. Extending the upper limit of frequency is possible with existing probe technology but is beyond the scope of this specification. Measurements may be ca

47、rried out in the frequency domain or in the time domain. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
