24、rmodulation in coaxial cable assemblies 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 que
25、stions 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 Publicatio
26、n(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 preparation. IEC co
27、llaborates 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 opinio
28、n 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. While all reasonable efforts are made to ens
29、ure 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 transparently t
30、o 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. Independent certificati
31、on 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 liability shall att
32、ach 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 (including legal fee
33、s) 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 of this publicati
34、on. 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. International Standard IEC 62037-2 has been prepared by technical committee 46: Cables,
35、 wires, waveguides, r.f. connectors, r.f. and microwave passive components and accessories. This bilingual version (2014-01) corresponds to the monolingual English version, published in 2012-11.The text of this standard is based on the following documents: FDIS Report on voting 46/408/FDIS 46/420/RV

37、 list of all the parts in the IEC 62037 series, published under the general title Passive RF and microwave devices, Intermodulation level measurement can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indica
38、ted 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, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it con
39、tains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 62037-2 IEC:2012 5 PASSIVE RF AND MICROWAVE DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 2: Measurement of passive intermodulation in c
40、oaxial cable assemblies 1 Scope This part of IEC 62037 defines a procedure to measure levels of passive intermodulation generated by a coaxial cable assembly. This test method is applicable to jumper cables, i.e. cable assemblies intended to provide interface flexibility between rigid devices. 2 Nor
41、mative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments
42、) applies. IEC 62037-1:2012, Passive RF and microwave devices, intermodulation level measurement Part 1: General requirements and measuring methods 3 Abbreviations DUT Device under test PIM Passive intermodulation 4 Test set-up Set-up 1 and set-up 2 are applicable in this PIM-test. Either set-up 1 (
43、reverse method, see 6.2.2 of IEC 62037-1:2012), or set-up 2 (forward method, see 6.2.3 of IEC 62037-1:2012), may be used for cable assemblies, provided that the attenuation of the assembly is not greater than 1 dB. For higher attenuation, the reverse method shall be used. The connector under test sh
44、ould be clamped and mechanically secured to prevent its movement during the test. A describable and repeatable mechanical stress is applied to the DUT. This mechanical stress is defined by a distance d, between the end of the cable-entry (the last rigid mechanical point of the connector) and the poi
45、nt of the deflection, and circular movement around the cable axis with a radius r. This test shall be performed on each end independently. An example of a test set-up is shown in Figure 1. The cable movement is depicted in Figure 2. The rotational radius (r) and distance (d) is defined in Table 1. T

It is recommended to rotate the cable clockwise. 5 Procedure The procedure is as follows: a) calibrate the set-up; b) connect the DUT to the set-up; c) read the PIM before applying mechanical stress; d) apply mechanical stress to the DUT according to Table 1; e)
