SIST EN 60512-28-100:2013

Connectors for electronic equipment - Tests and measurements - Part 28-100: Signal integrity tests up to 1 000 MHz on IEC 60603-7 and IEC 61076-3 series connectors - Tests 28a to 28g

This part of IEC 60512 specifies the test methods for transmission performance for IEC 60603-7 and IEC 61076-3 series connectors up to 1 000 MHz. It is also suitable for testing lower frequency connectors, however the test methodology specified in the detailed specification for any given connector remains the reference conformance test for that connector.
The test methods provided here are:
– insertion loss, test 28a;
– return loss, test 28b;
– near-end crosstalk (NEXT) test 28c;
– far-end crosstalk (FEXT), test 28d;
– transverse conversion loss (TCL), test 28f;
– transverse conversion transfer loss (TCTL), test 28g.
For the transfer impedance (ZT) test, see IEC 60512-26-100, test 26e.
For the coupling attenuation, see IEC 62153-4-12.

La CEI 60512-28-100:2013 spécifie les méthodes d'essais pour les performances des transmissions pour des connecteurs conformes aux séries CEI 60603-7 et CEI 61076-3 jusqu'à 1 000 MHz. Elle s'applique également aux essais de connecteurs de plus basses fréquences, mais la méthodologie d'essai spécifiée dans la spécification particulière pour tout connecteur donné reste l'essai de conformité de référence pour le connecteur en question. Les méthodes d'essai spécifiées ici sont:  - perte d'insertion, essai 28a,  - affaiblissement de réflexion, essai 28b,  - paradiaphonie (NEXT), essai 28c,  - télédiaphonie (FEXT), essai 28d,  - perte de conversion transverse (TCL), essai 28f,  - perte de transfert de conversion transverse (TCTL), essai 28g. Pour l'essai d'impédance de transfert (ZT), voir la CEI 60512-26-100, essai 26e. Pour l'affaiblissement de couplage, voir la CEI 62153-4-12.

Konektorji za elektronsko opremo - Preskusi in meritve - 28-100. del: Preskusi signalne celovitosti do 1 000 MHz na konektorjih serij IEC 60603-7 in IEC 61076-3 - Preskusi od 28a do 28g

Ta del IEC 60512 določa načine testiranja delovanja prenosa za IEC 60603-7 in IEC 61076-3 serijske konektorje do 1000 MHz. Primerna je tudi za testiranje konektorjev z nižjimi frekvencami, vendar metodologija testiranja, določena v podrobnih specifikacijah za kateri koli konektor ostaja test referenčne skladnosti za posamezni konektor.
V nadaljevanju so podane naslednje preskusne metode:
– dodano dušenje, preskus 28a;
– povratno dušenje, preskus 28b;
– bližnji presluh (NEXT), preskus 28c;
– daljni presluh (FEXT), preskus 28d;
– prečno dušenje pretvorbe (TCL), preskus 28f;
– prečno dušenje pretvorbe prenosa (TCTL), preskus 28g.
Za preskus impedance prenosa (ZT) glejte IEC 60512-26-100, preskus 26e.
Za slabljenje stikov glejte IEC 62153-4-12.

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 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)”). 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 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
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 international 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 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 indicated 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.
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 damage 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 publication. 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 all such patent rights.
International Standard IEC 60512-28-100 has been prepared by subcommittee 48B:

Part 28-100: Signal integrity tests up to 1 000 MHz
on IEC 60603-7 and IEC 61076-3 series connectors –
Tests 28a to 28g



1 Scope
This part of IEC 60512 specifies the test methods for transmission performance for
IEC 60603-7 and IEC 61076-3 series connectors up to 1 000 MHz. It is also suitable for
testing lower frequency connectors, however the test methodology specified in the detailed
specification for any given connector remains the reference conformance test for that
connector.
The test methods provided here are:
– insertion loss, test 28a;
– return loss, test 28b;
– near-end crosstalk (NEXT) test 28c;
– far-end crosstalk (FEXT), test 28d;
– transverse conversion loss (TCL), test 28f;
– transverse conversion transfer loss (TCTL), test 28g.
For the transfer impedance (ZT) test, see IEC 60512-26-100, test 26e.
For the coupling attenuation, see IEC 62153-4-12.
