Abstract

Den foreliggende oppfinnelse angår en frem- gangsmåte for å minimalisere fasefeilen (1) hos en sender/mottaker-enhet. For å muliggjøre enkel og rask justering av fasefeilen, blir et forut bestemt testsignal påtrykt via en forsinkelsesanordning (20) til inngangen av senderseksjonen (1) av sender/ mottaker-enheten; utgangssignalet fra sender- seksjonen (1) blir omformet til mottakerfrekvensen for mottakeren (2); mottakerfrekvens-signalet blir påtrykt mottakeren (2) i sender/mottakerenheten; utgangssignalet fra mottakeren (2) blir sammenlignet med det nevnte forut bestemte testsignal; og forsinkelsesanordningen (20) justeres på basis av resultatet av sammenligningen slik at fasefeilen hos senderen (1) blir minimalisert. Oppfinnelsen angår også en sender/mottaker-enhet i hvilken fremgangs- måten ifølge oppfinnelsen kan anvendes.
