CA 2424276

The present invention provides a signal integrity measurement and apparatus which allows for signal characteristics to be measured by obtaining samples taken at the midpoint (3) of the data stream. The invention provides a measurement device (57; 83) that is suitable for use in the field to provide a measurement of signal characteristics within transmitted data streams. The invention is particularly suitable for field measurement of signal characteristics of data streams or continuous in-line monitoring of signal characteristics within transmitted data streams. The signal characteristics include, but are not limited to eye opening (21), jitter (23), noise (24), slope efficiency, average power and peak-to-peak amplitude.

La présente invention concerne un procédé et un dispositif permettant de mesurer l'intégrité d'un signal. Ce procédé et ce dispositif permettent de mesurer les caractéristiques d'un signal grâce à des échantillons prélevés au point milieu (3) du flot de données. Cette invention concerne un dispositif de mesure (57; 83) conçu pour être utilisé sur place de manière à obtenir une mesure des caractéristiques du signal dans les flots de données transmis. L'invention convient tout particulièrement à la mesure sur place des caractéristiques d'un signal dans des flots de données ou à la surveillance continue en ligne des caractéristiques d'un signal dans des flots de données transmis. Les caractéristiques d'un signal comprennent, entre autres, l'ouverture de l'oeil (21), la gigue (23), le bruit (24), l'efficacité de la pente, la puissance moyenne et l'amplitude crête à crête.
