IEC 60512-28-100:2019
(Main)Connectors for electrical and electronic equipment - Tests and measurements - Part 28-100: Signal integrity tests up to 2 000 MHz - Tests 28a to 28g
Connectors for electrical and electronic equipment - Tests and measurements - Part 28-100: Signal integrity tests up to 2 000 MHz - Tests 28a to 28g
IEC 60512-28-100:2019 specifies the test methods for signal integrity and transmission performance for connectors specified in respective parts of IEC 60603-7, IEC 61076-1, IEC 61076-2, and IEC 61076-3 standards for connecting hardware applications up to 2 000 MHz. It is also suitable for testing lower frequency connectors, however, the test methodology specified in the detail specification for any given connector remains the reference conformance test for that connector. The above list of connector series of standards does not preclude referencing this document in other connector manufacturer’s specifications or published standards. Test procedures provided herein 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.
Other test procedures referenced herein are:
- transfer impedance (ZT), see IEC 60512-26-100, test 26e.
- for coupling attenuation (aC), see IEC 62153 4 12.
This second edition cancels and replaces the first edition, issued in 2013, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- The title is revised from 1 000 MHz to 2 000 MHz to reflect the range of frequencies which may be tested.
- All tables and requirements have been revised up to 2 000 MHz.
Key words: Connectors, Signal Integrity Tests
Connecteurs pour équipements électriques et électroniques - Essais et mesures - Partie 28-100: Essais d’intégrité des signaux jusqu’à 2 000 MHz - Essais 28a à 28g
L'IEC 60512-28-100:2019 spécifie les méthodes d’essai d’intégrité des signaux et de qualité de transmission pour des connecteurs spécifiés dans les parties respectives des normes IEC 60603-7, IEC 61076-1, IEC 61076-2 et IEC 61076-3 pour des applications de matériel de connexion jusqu’à 2 000 MHz. Elle s’applique également aux essais de connecteurs de fréquences inférieures, mais la méthodologie d’essai stipulée dans la spécification particulière pour tout connecteur donné reste l’essai de conformité de référence pour le connecteur en question. La liste ci-dessus de séries de normes concernant les connecteurs n’exclut pas le fait de faire référence au présent document dans d’autres normes publiées ou spécifications des fabricants de connecteurs. Les procédures 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.
Les autres procédures citées ici en référence sont:
- impédance de transfert (ZT), voir l’IEC 60512-26-100, essai 26e;
- pour l’affaiblissement de couplage (aC), voir l’IEC 62153 4 12.
Cette deuxième édition annule et remplace la première édition parue en 2013 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- Le titre a été modifié, 1 000 MHz a été remplacé par 2 000 MHz afin de refléter la plage des fréquences qui peuvent être soumises à des essais.
- Tous les tableaux et toutes les exigences ont été révisés jusqu’à 2 000 MHz.
