Abstract

For å bestemme driftsparametere for en høyfrekvent kraftforsterker (1) (for eksempel kompleks lede- og returspenning eller -effekt, kompleks belastningsimpedans, refleksjon eller standbølgespenningsforhold) på forbindelseslinjen (3) mellom utgangen fra den høyfrekvente kraftforsterkeren (1) og en kompleks belastning, spesielt en antenne (4), blir en analogt målt spenning Uu som er proporsjonal med den komplekse spenningen på forbindelseslinjen, og en analogt målt spenning Ui som er proporsjonal med den komplekse strømmen på linjen (3), bestemt ved hjelp av en Buschbeck-koblingsanordning. Disse målte spenningene blir digitalisert, og de nødvendige driftsparameterne kan så beregnes i en beregningsenhet (7) ut fra disse digitale verdiene.
