| Abstract: | This paper introduces a new arbitrary waveform generator which is designed based on a USB chip CH375,a MCU chip ADuC842 and a high speed DDS chip AD9850,in which the system general structure,the hardware circuit of waveform generation and the design of interface between CH375 and MCU have been introduced in detail. This device realizes the storage and replay of special waveform data,the generation of usually used function waveform,and also the convenient adjustability of frequency,phase and amplitude of the waveform. |
