单通道信号源构成多通道信号源技术研究

摘要

To utilize the multichannel signal source in the laboratory condition of only having single channel signal sour⁃ces,the method of how to use some single channel signal sources to constitute the multichannel signal source is researched. An implementation scheme using some single channel signal sources to constitute the multichannel signal source is proposed. The connection mode among the instruments are described and tested to analyze the merits of the proposed scheme. According to the experimental results,the relationship of phase difference and frequency among the multiple output signals is obtained when the multichannel signal source is applied. On this basis,the final implementation scheme is determined to realize the multichannel signal source constituted of some single channel sources.%为了在只有单通道信号源的实验室条件下，实现能够使用多通道信号源的目标，研究了如何将多台单通道信号源构成多通道信号源。提出一种多台单通道信号源构成多通道信号源的实现方案，详细说明了仪器之间的连接方式，并进行实验，分析了所提出方案的优劣。最后，根据实验结果，得出了多台单通道信号源构成多通道信号源时多路输出信号间的相位差与频率之间的关系，并由此确定了最终的实现方案，实现了多台单通道信号源构成多通道信号源。
