Abstract

Oppfinnelsen tilveiebringer et fordelaktig og pålitelig sløyfeutstyr (60) for å etablere en testsløyfe for overvåkning av tilstanden for en radiostasjon som innbefatter minst to antenner. Sløyfeutstyret (60) omfatter inngangsporter (61, 61'), utgangsporter (69, 69') og en styrbar velger-svitsj (62) hvormed signalet fra én inngangsport (61') velges til å gå til minst én utgangsport (69, 69'). Sløyfeutstyret er innrettet på en slik måte at dets inngangsporter (61,61') er koplet til utgangene på sendere (TX, TX'), og utgangsporter (69, 69') til inngangen på en mottaker (RX, RX'). Forskjellige testsløyfer for overvåkning av tilstanden for sendere, mottakere og antenner i en radiostasjon kan etableres ved hjelp av sløyfeutstyret.
