摘要
介绍了一种基于PC机、FPGA和数字频率合成技术(DDS)的隔离型任意波信号发生器的设计方法;利用LabVIEW虚拟仪器设计上位机软件控制平台,利用基于FPGA的DDS技术实现下位机硬件设计,通过局域网将软硬件平台连接起来构成具有64路有独立地线系统的模拟信号源,输出频率(DC)达8 kHz,幅度0～70V。
A method of isolated arbitrary waveform generator design based on PC, FPGA and digital frequency synthesis （DDS） is introduced. The LabVIEW virtual instrument is used to design PC control software plat- form, the hardware design of lower machine is realized by using DDS technology of FPGA-based. With the LAN, hardware and software platform is connected together to form the DDS analog signal source, whose output frequency is DC up to 8 kHz, and magnitude is from 0 to 70 V.
