矢量网络分析仪系统锁相技术

The system Phase locking Technology of vector network analyzer

系统锁相技术是矢量网络分析仪的关键技术,其主要作用是保证YTO输出频率和参考频率严格同步。本文详细介绍了系统锁相技术中辅助锁相电路的设计,阐述了此辅助电路是如何有效缩短扫描时间,进而提高整个矢量网络分析仪测试速度。

system Phase locking Teehnology is very important in vector network analyzer, it insure in-phase between frequency of YTO and frequency of reference.. In this paper, The design of assistant of PLL was introduced detailed, and the causation how this design shortened scanningtime was explained. The time of scanning was shortened, the time of measure was shortened corresponding.
