| Abstract: | The paper introduces a method to develop a high precise DDS signal source based on LabVIEW and SOPC.The system is composed of two parts,PC software and firmware of Arbitrary Waveform Generator,and the communication between the two sections is achieved by UART.The data of arbitrary waveforms are edited and downloaded using PC software.In the design,DDS module and MCU module are integrated into a single FPGA chip.So the performance such as integration,stability and expansibility are greatly improved.By means ... |
