摘要：

This system mainly controlled by the minimum system which consists of the Single-Chip Microcomputer and FPGA, is based on the technology of the Direct Digital Frequency Synthesis(DDS) to achieve the function of generating, undistorted sinusoidal signal with integrated chip of DDS, whose frequency ranges from 1Hz to 20MHz with stability of 10-5.Via power amplifier, the amplitude of the output signal on the 50 Omega load measures up to 6V +/- 1V.Besides,the system can also generate modulation signals such as AM, FM, ASK, PSK and so on. The system also realizes good human-computer interaction with matrix keyboard and LCD which can assign function and display the correlative information.
