发明名称 Passive system and method to determine distortion in an RF satellite chain
摘要 A system 10 that is used for analyzing a broadcast system includes a receiving device 60 that generates a baseband demodulated RF signal and digitizes the RF signal to form a digitized signal. A data capture module such as the IQ monitor board 90 is coupled to the receiving device 60 for acquiring samples of the digitized signal. A computer is communication with the data capture module. The computer processes the samples of the digitized signal to obtain a broadcast system response and an inverse broadcast system response. The display generates a display corresponding to the broadcast system response and the inverse system response.
