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)

This document 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.

IEC 60512-28-100:2019 est disponible sous forme de IEC 60512-28-100:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

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.
Mots-clés: connecteurs, essai d’intégrité des signaux

Konektorji za električno in elektronsko opremo - Preskusi in meritve - 28-100. del: Preskusi signalne celovitosti do 2000 MHz - Preskusi od 28a do 28g (IEC 60512-28-100:2019)

Ta dokument določa preskusne metode za signalno celovitost in zmogljivost prenosa za konektorje, določene v zadevnih delih standardov IEC 60603-7, IEC 61076-1, IEC 61076-2 in IEC 61076-3, za povezovanje strojne opreme do 2000 MHz. Primeren je tudi za preskušanje konektorjev z nižjimi frekvencami, vendar metodologija preskušanja, določena v podrobnih specifikacijah za kateri koli konektor, ostaja preskus referenčne skladnosti za ta konektor. Zgornji seznam skupin standardov za konektorje ne izključuje sklicevanja na ta dokument v specifikacijah drugih proizvajalcev konektorjev ali objavljenih standardih. Preskusni postopki, navedeni v tem dokumentu, so: – 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. Drugi preskusni postopki, na katere se sklicuje ta dokument, so: – impedanca prenosa (ZT), glej IEC 60512-26-100, preskus 26e. – za slabljenje stikov (aC) glej IEC 62153-4-12.
