| Abstract: | One kind of signal testing instrument is mainly designed.It tested other objects' processeing all kinds of signals.Through measureing the the information feeded back from measured objects,the instrument measured the objects' working conditions.DSP and FPGA are mainly used to finish the design,and a PC inputed parameters of signal and D/A are recovered and outputted the signal.Doppler signal is used to simulate,and the experiment indicated that the testing effect was very good.The system's whole function and... |
