摘　　要：针对高采样率大带宽复杂波形信号的测试需求,设计实现了一种宽带任意波形发生器。采用国产高速DAC芯片、高性能FPGA和宽带可控增益放大器的设计方法,国产DAC集成CML数据接口,保证了传输带宽。测试结果表明:该系统支持10 GSPS采样率、4 GHz带宽的任意波形信号输出,具有良好的性能。For the testing requirement of complex waveform signals with high sampling rate and bandwidth,a high bandwidth arbitrary waveform generator(AWG)is designed and realized.The AWG adopts high speed domestic DAC,high performance FPGA and Wideband Gain Controlled Amplifier.The usage of CML data interface in the domestic DAC leads to the high transmission bandwidth.Experiments show that the system has good performance which supports arbitrary waveform signals with sampling rate 10 GSPS and bandwidth 4 GHz.
