Abstract
this paper introduces an output method of arbitrary waveform signal on the FPGA by uses DDS principle. Arbitrary waveform dates produced by the upper machine are downloaded to the waveform RAM of the DDS through the serial port, and realize the control of frequency and phase by using single-chip microcomputer. The upper machine with using LabWindows/CVI software design, realizes arbitrary waveform output.
