Abstract

Keksinnön kohteena on menetelmä ja menetelmän toteuttava järjestely lähetinvastaanottimen lähetinosan (100) ja vastaanotinosan (102) testaamiseksi. Menetelmässä sekoitetaan lähetinosan signaali sekoitussignaaliin vastaanotinosaan kytkettävän signaalin muodostamiseksi, joka signaali kytketään vastaanotinosaan ja verrataan mainittua kytkettyä signaalia lähetinosan signaaliin lähetinvastaanottimen testaamiseksi. Sekoitussignaali muodostetaan välittämällä lähetinosan ja/tai vastaanotinosan toiminnassa käytössä olevan signaaligeneraattorin (202) muodostama signaali ainakin kahteen signaalihaaraan, jakamalla signaalihaaroissa signaali ainakin kahdeksi eri signaalihaarojen kesken eritaajuiseksi signaaliksi ja muodostamalla eritaajuisista signaaleista sekoitussignaali.
