Design of DDS Function Generator Based on PXI-Bus Control

本文从工程应用角度出发,在深入研究PXI总线和直接数字频率合成(DDS)技术的基础上,研发和设计了基于PXI总线控制的函数发生器模块。利用PXI专用接口芯片PCI9030完成PXI接口电路及模块驱动开发,接口性能符合要求。信号产生模块采用先进的DDS技术,并在ARM主控平台上实现,采用标准3U尺寸设计。最后测试验证了电路的性能指标满足设计要求。

From the engineering point of view, based on in-depth study PXI bus and Direct Digital Synthesis （DDS） technology, the function generator module based on the PXI bus control has been designed. Using PXI -specific interface chip PCI9030, the PXI module interface circuit was completed and driver was development, Interface performance to meet the requirements. Signal generation module uses advanced DDS technology, and ARM host control platform to achieve, a standard 3U size design. Finally test the circuit performance is verified to meet the design requirements.
