Abstract

For å bestemme driftsparametre for en kraftforsterker (1) (for eksempel den komplekse belastningsimpedansen eller den komplekse lede- og retureffekten eller refleksjonsfaktoren eller stambølgespenningsforholdet) på forbindelsesledningen (3) mellom utgangen fra kraftforsterkeren (1) og en kompleks belastning (4), blir de komplekse analoge lede- og returspenningene på forbindelsesledningen (3) bestemt ved hjelp av en analog koplingsanordning (5). Disse analoge spenningene blir så hver digitalisert og konvertert ned til basisbåndet ved hjelp av digitale nedkonverterere. Fra disse digitale verdiene som svarer til absolutt verdi og fase for de komplekse lede- og returspenningene og som er til stede i basisbåndet, blir så de nødvendige driftsparameterne beregnet i en datamaskin (12).
