某新型导弹发控设备检修信号源设计

The Design of Maintenance Signal Source for a New Missile Launch and Control Equipment

介绍一种基于CPLD和DDS技术,实现了某新型导弹发控设备检修所需信号源,它可以产生输出频率、幅值、相位可调的正弦波以及伪随机信号,解决了装备检修时无信号源的难题。信号源系统稳定可靠、精度高、具有良好的可扩展性。

This paper adopts a CPLD and DDS （digital frequency synthesis） technology to achieve the required maintenance signal source for a new missile launch and control equipment. It can produce an output frequency, amplitude, sine wave with the adjustable phase and pseudo random signals. It solves the problem of no signal source in the equipment maintenance. The system has stable and reliable source, high precision and good scalability.
