可程控的延时网络设计方法

Design of programmable controllable delay network

延时网络是军用电子信息系统模拟仿真电磁环境所必需的一种设备。本文从基于参考通道与测试通道比值测量的测试方法入手,重点介绍一种可程控延时网络的软硬件设计方法及技术实现途径,文中在最后给出了程控延时网络的测试数据与分析结果,结果表明所设计的可程控延时网络的延时误差不超过±0.2 ns,满足技术指标的要求,文中论述的方法正确、可行。

Delay network is a necessary kind of device which is used in the electromagnetic-condition simulation of military electronic information systems. In this paper, it begins with the test method based on ratio of referenced channel to test channel, introduces the method to design and realize one programmable delay network with hardware and software. And in the end of the paper, it not only gives the test data and analysis result of the delay network which indicates the delay error is within ±0. 2 ns and meets the requirement but also shows the method in this paper is correct and feasible.
