[Abstract]:Signal generator, also called signal source, is one of the important electronic instruments widely used in the field of electronic measurement, which is used to generate electrical test signal with specific parameters required by the circuit under test. With the rapid development of computer technology and microelectronics industry, direct digital frequency synthesizer (DDS) technology has become the main trend of high performance digital signal generator design, with the characteristics of high precision, arbitrary modulation waveform and so on. With the continuous rapid development of network technology, LXI instruments based on LAN bus technology have also been developed and applied. The research content of this thesis is the design of C class LXI digital signal generator based on DSP BF531 processor and DDS technology. In this paper, the design of LXI signal generator is mainly composed of two parts: the firmware of signal generator and the LXI communication interface module. From the point of view of software design, the software design and implementation of LXI signal generator are described in detail. The firmware program of the signal generator includes the basic configuration of the BF531 chip, the communication interface, the logic design of the man-machine interface, the serial port communication and the key control of the SPI port instrument. At the same time, the keyboard board. LXI communication interface module based on CPLD EPM240T100C5 is designed. The hardware platform is DM9000 chip based on embedded processor. The software is realized by transplanting embedded uip protocol stack in firmware and developing program in application layer. Including VXI-11ONC / RPC and PORTMAP protocol porting SCPI command interpreter to build the Web server and develop CGI and so on. At the end of the paper, the function of signal generator is tested systematically. This paper summarizes the main achievements of instrument software design, and puts forward some ideas and plans for related research and function expansion.
