Cable networks for television signals, sound signals and interactive services - Part 101: System performance of forward paths with all-digital channels load (TA/5) (IEC 60728-101:2016)

This part of IEC 60728 is applicable to any cable network (including individual receiving
systems) distributing only digital channels having in the forward path a coaxial cable output
and primarily intended for television and sound signals operating between about 30 MHz and
3 000 MHz.
This standard specifies the basic methods of measurement of the operational characteristics
of a cable network having coaxial cable outputs in order to assess the performance of these
systems and their performance limits.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 101: Performances des systèmes de voie directe soumis à une charge de porteuses exclusivement numériques (IEC 60728-101:2016)

L'IEC 60728-101:2016 s'applique aux réseaux de distribution par câbles (y compris les systèmes individuels de réception) distribuant uniquement des canaux numériques, comportant dans le sens descendant une sortie à câble coaxial et essentiellement destinés aux signaux de télévision et aux signaux de radiodiffusion sonore, fonctionnant approximativement entre 30 MHz et 3 000 MHz. La présente norme spécifie les méthodes fondamentales pour la mesure des caractéristiques opérationnelles d'un réseau de distribution par câbles comportant des sorties à câbles coaxiaux dans le but d'évaluer la performance de ces systèmes ainsi que leurs limites de performances.

Ta del standarda IEC 60728 se uporablja za katero koli kabelsko omrežje (vključno s posamičnimi sistemi za sprejem) za porazdelitev izključno digitalnih kanalov, ki v naprejšnji poti vključujejo koaksialni kabelski izhod ter so namenjeni za prenos televizijskih in zvokovnih signalov s frekvenco med približno 30 MHz in 3000 MHz.
Ta standard določa osnovne metode merjenja obratovalnih značilnosti kabelskega omrežja s koaksialnimi kabelskimi izhodi, da bi se ocenile lastnosti teh sistemov ter omejitve njihovega delovanja.
