基于FPGA的多通道高速波形发生器设计

Multi-Channel High Speed Wave Generator on FPGA

为了产生多通道的高速信号,波形发生器以FPGA为核心,结合高速高精度数模转换器和高速运算放大器,采用DDS技术来实现高速信号的产生。波形发生器采用PCI总线与上位机进行通信,上位机通过发送控制命令改变波形发生器输出信号的种类、频率、相位。波形发生器还可以进行AM调制、FM调制、ASK调制、PSK调制和FSK调制等。

In order to achieve multi-channel high-speed waveform generator,the waveform generator is based on FPGA,combined with high-speed high-precision DAC and high-speed operational amplifier,using DDS technology to achieve high-speed signal.Waveform generator uses PCI bus to communicate with the host computer,host computer by sending control commands to change the waveform generator output signal of the type,frequency and phase.Waveform generator can also achieve AM modulation,FM modulation,ASK modulation,PSK modulation,FSK modulation.
