Abstract

Die Erfindung bezieht sich auf eine Meßeinrichtung (29) für die Schnittstelle (2) einer Übertragungsstrecke (1) mit einer Vollduplex-Übertragung im Zweidrahtgleichlageverfahren, bei der eine die Schnittstelle (2) nachbildende Einrichtung (8) vorhanden ist, mit deren Hilfe das auf Übertragungsstrecke (1) hinlaufende Signal (Uhin) vom rücklaufenden Signal (Urück) getrennt werden kann. Um an der Schnittstelle (2) der Übertragungsstrecke (1) während des Übertragungsbetriebes Jittermessungen unter Verwendung eines üblichen Jittermeßgerätes (26) genau durchführen zu können, ist bei der erfindungsgemäßen Meßeinrichtung (29) an einen Subtrahierer (15) ein Differenzierglied (19) mit einem nachgeschalteten Komparator (25) angeschlossen, wobei der Komparator (25) ausgangsseitig mit dem Jittermeßgerät (26) verbunden ist.
