23、and definitions Near-field scan data exchange format FOREW ORD 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-operat
24、ion 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, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “
25、 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, governmental and non-governmental organizations liaising with the IEC also participate in this prep
26、aration. 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 or agreements of IEC on technical matters express, as nearly as possible, an international cons
27、ensus 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 international use and are accepted by IEC National Committees in that sense. W hile all reasonable efforts
28、 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications
29、 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 indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Indepen
30、dent 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. 6) All users should ensure that they have the latest edition of this publication. 7) No lia
31、bility 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 damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (inc
32、luding 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 publication. Use of the referenced publications is indispensable for the correct application o
33、f 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 all such patent rights. The main task of IEC technical committees is to prepare International S
34、tandards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “ state of the art“ . IEC TR 61967-1-1, which is a technical report, has been prep
35、ared by subcommittee 47A: Integrated circuits, of IEC technical committee 47: Semiconductor devices. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant changes with respect to th
36、e previous edition: Addition of: PD IEC/TR 61967-1-1:2015 6 IEC TR 61967-1-1:2015 IEC 2015 4.11 3D objects; Binary data files; Piece-wise linear time domain and frequency domain data; Vectors permitting rotation and offset of measurement and DUT reference planes; Transducer gain and probe factor can

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “ http:/ / webstore.iec.c

A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication i

PD IEC/TR 61967-1-1:2015IEC TR 61967-1-1:2015 IEC 2015 7 INTRODUCTION Near-field scan measurements, as described for e
42、xample in IEC TS 61967-3 11or IEC TS 62132-9 2 , and simulations generate a large amount of data. Many different formats are used for storing the data, thereby rendering its exchange extremely difficult. The proposed format is intended to facilitate exchange of near-field scan data between industria
43、ls, academics, EDA tool vendors and end customers. It is based on the well-known X ML format, which is both machine and human readable. Its structure allows the files to be generated and processed on any operating system. In order to limit the file size, it is possible to store the information and d
44、ata in a single file or multiple files. Moreover, the ASCII-based X ML format allows the files to be compressed to a very high level with readily available compression software. The three conventional coordinate systems (Cartesian, cylindrical and spherical) are supported by the proposed exchange fo
45、rmat. Information on the device under test, the test set-up, the probe, etc., is also included in the files. Notes and links to external documents allow complex test environments to be well described. The version of the exchange format described in this technical report is 2.0. Future revisions will
46、 add items, such as new keywords and rules, considered to be “ enhancements“ to Version 1.0. Consequently, all future revisions will be considered supersets of Version 2.0, allowing backward compatibility. _ _ _ _ _ _ _ _ _ _ _ _ _ 1Figures in square brackets refer to the Bibliography.

48、The described exchange format could also be used for near-field scan data generated by simulation or computation software. It should be noted that, although it has been developed for near-field scan, its use is not restricted to this application. The exchange format can be applied to emission and im
49、munity near-field scan data in the frequency and time domains. The scope of this technical report includes neither the methods used for the measurements or simulations, nor the software and algorithms used for generating the exchange file or for processing or viewing the data contained therein. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and a
