摘　　要：随着通信技术的快速发展,信号从原来的单通道信号发展到多通道信号,信号也从模拟信号发展到数字信号,同时对信号的相位稳定性的要求也越来越高。本文实现了能产生多通道高稳定性相参信号的系统搭建与验证。该系统搭建是基于Keysight M8195A任意波形发生器为核心仪器,以脉冲源产生触发信号和时钟信号,用示波器来检测信号的相位稳定性。实验结果证明,该系统能够根据对于任意波形发生器的设置来产生相应的多通道信号,并且通道间相位稳定性达到皮秒级别。这能为诸多领域的研究和应用提供一个完美的多通道高稳定相参信号的产生平台,具有很大的实际应用价值。With the rapid development of communication technology, signal have developed into multi-channel and digital modulated signal from single-Channel and analog signal. Meantime, the requirements of phase signal stability is increasing. This paper realized the establishment and implement of multi-channel high stability phase-coherent signal generating system. The establishment of the system is based on Keysight M8195A arbitrary waveform generator as the core instrument, a pulse source generator provides the trigger signal and the clock signal, a oscilloscope to detect the phase stability of the signal. Experiment results show that, the system can generate multi-channel high stability phase-coherent signal based on the setting of arbitrary waveform generator, and the phase stability of different channel is small to picosecond level. This provides a perfect platform to generate multi-channel high stability phase-coherent signal for applications in many fields of research, owns great practical value.
