Abstract
(DE)
Eine Messvorrichtung zum Messen der Hüllkurvenleistung und des Leistungsmittelwerts eines Hochfrequenzsignals hat einen Detektor (2) zum Detektieren des Hochfrequenzsignals und zum Erzeugen eines analogen Detektorsignals, einen Analog/Digital-Wandler (6) zum Erzeugen eines digitalen Signals und eine Auswerteeinrichtung (8, 9) zur Auswertung des digitalen Signals. Zwischen dem Detektor (2) und dem Analog/Digital-Wandler (6) ist eine Dither- Einspeiseeinrichtung (11, 26) zum Einspeisen eines Dithersignals und zwischen dem Analog/Digital-Wandler (6) und der Auswerteeinrichtung (8, 9) ist eine Dither- Eliminationseinrichtung (12, 15, 27) zum Eliminieren des Dithersignal angeordnet, wobei die Einspeiseeinrichtung (11, 26) für die Messung der Hüllkurvenleistung ein anderes Dithersignal als für die Messung des Leistungsmittelwerts einspeist.
(EN)
The invention relates to a measuring device for measuring the peak envelope power and the average power of a high frequency signal, comprising a detector (2) for detecting the high frequency signal and for producing an analog detector signal, an analog/digital converter (6) for producing a digital signal, and an evaluation device (8, 9) for evaluating the digital signal. A dither feeding device (11, 26) is arranged between the detector (2) and the analog/digital converter (6) for feeding a dither signal and a dither elimination device (12, 15, 27) is arranged between the analog/digital converter (6) and the evaluation device (8, 9) for eliminating the dither signal. The feeding device (11, 26) for measuring the peak envelope curve injects another dither signal that is different from that used for measuring the average power.

Dispositif de mesure destiné à la mesure de la puissance d'une courbe enveloppante et de la valeur moyenne de la puissance d'un signal haute fréquence comprenant un détecteur (2) pour détecter le signal haute fréquence et générer un signal détecteur analogique, un convertisseur analogique/numérique (6) pour générer un signal numérique et un dispositif d'évaluation (8, 9) pour évaluer le signal numérique. Un dispositif d'injection de vibrations (11, 26) implanté entre le détecteur (2) et le convertisseur analogique/numérique (6) permet d'injecter un signal de vibrations (11, 26) et un dispositif d'élimination des vibrations (12, 15, 27) implanté entre le convertisseur analogique/numérique (6) et le dispositif d'évaluation (8, 9) permet d'éliminer le signal de vibrations. Le dispositif d'injection (11, 26) injecte pour la mesure de la puissance de la courbe enveloppante un signal de vibrations différent de celui pour la mesure de la valeur moyenne de la puissance.
