Abstract
Ovaj rad prikazuje rezultate razvoja analizatora spektra za nadzor VSAT sustava. Analizirane su različite metode mjerenja spektralnog sadržaja signala i uspoređena odgovarajuća sklopovska rješenja. Za heterodinski analizator spektra sa prebrisavanjem definirani su parametri vrednovanja. Projektiran je i praktično izveden heterodinski analizator spektra za nadzor komunikacijskog VSAT sustava. Analizator je konstruiran kao superheterodinski prijemnik sa trostrukom pretvorbom frekvencije i sinteziranim lokalnim oscilatorima čijim se frekvencijama upravlja pomoću personalnog računala. Informacija o nivou snage pojedine komponente spektra dobiva se analogno digitalnom pretvorbom istosmjernog upravljačkog napona petlje automatske regulacije pojačanje posljednjega međufrekvencijskog pojačala. Rezultati mjerenja na realiziranom analizatoru spektra pokazali su dobro slaganje sa teoretskom analizom.
Abstract (english)
This thesis reports the results of the development of spectrum analyzer for surveillance of VSAT communication system. Different methods of spectrum analysis have been analysed and appropriate hardware designs have been compared. Technical parameters of the heterodyne spectrum analyzer have been defined. The spectrum analyzer was realised as a three-stage heterodyne receiver with synthesised local oscillators, frequencies of which were controlled by personal computer. The information of the power level of the measured frequency component was obtained by analog to digital conversion of the DC signal of the of the last IF amplifier automatic gain control. The measurements on the realised analyzer showed good agreement with theory.
