| Abstract: | In view of the high price of special instrument,an amplitude-frequency characteristic measurement system based on general signal generator and spectrum analyzer was developed independently.The software was developed with LabVIEW.The following functions are realized,including automatic control of instruments,data processing,analyzing,indicating,saving and so on.A pre-power amplifier was measured by the system,and the measured data were compared with those of the Agilent N5230A vector network analyzer.The result validated the effectiveness of the developed amplitude-frequency characteristic test system. |
