Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Phasenberechnung aus den Dämpfungswerten mittels Hilberttransformation bei FDR-Messungen, wobei das Messsystem eine Signalquelle für ein Messsignal, ein mit der Signalquelle verbundenes Kopplungsglied und ein mit dem Kopplungsglied verbundenes Messobjekt aufweist. Der vom Messobjekt reflektierte Anteil des Messsignals wird über das Kopplungsglied ausgekoppelt und an einer Senke gemessen. Erfindungsgemäss ist zwischen dem Kopplungsglied und dem Messobjekt ein Dämpfungsglied in den Signalpfad geschaltet. Das Dämpfungsglied kann auch im Kopplungsglied enthalten sein.
