| Abstract: | As a complicated communication signal GSM signal is of great measurement significance. By building up the GSM measurement network by Agilent E4438C vector signal generator, E4404B spectrum analyzer and GBIB bus, and based on the measurement and analysis of time and frequency domains of GSM signal, the carrier characteristics and frequency of GSM signal are comprehensively studied. All this in helpful in grasping various parameters of GSM signal. It also proves the correctness in adopting the GMSK modulation method in GSM system, and thus provides a theoretical foundation for systematic and automatic measurement of GSM mobile terminal. |
