Arbitrary waveform generators are important instruments for testing and measuring equipment, and they are widely used in the field of current measurement and control technology of the aerospace. The current market mature arbitrary waveform generators are foreign products or domestic manufacturers based on foreign FPGA and DAC developed products. In order to break the monopoly of technology, and improve the domestic arbitrary waveform generator of independent technical support capabilities, it is more important to develop arbitrary waveform generators based on domestic chips. With the improvement of domestic chip design technology, the performance of domestic FPGA and DAC has been improved, and has been widely used. The PXI bus, as one of the main bus types in the current instrument area, meets the communication requirements of most test instruments.Based on domestic FPGA and DAC, from the hardware design and software design two aspects, successfully developed a PXI bus arbitrary waveform generator module with sample rate up to 100MSa/s, and output a 43MHz signal. Through the test of the function and performance of the module, fully meet the requirements of the module indicators, fully proved that the domestic chip in the engineering design of the performance characteristics.
