基于LabVIEW的EDFA自动测试系统设计

EDFA automated test system based on LabVIEW

开发了一种EDFA自动测试系统:按照时域法测量原理设计了硬件系统,利用GPIB接口对系统的各个器件进行自动控制,实现了全自动测量,提高了测试效率,降低了测试难度,减少了人为误差。系统软件采用LabVIEW编制,采用了分层模块化设计,具有高内聚、松散耦合的特点,软件的修改和维护容易,可重用性和可扩展性强。

A new fully automated EDFA test system was implemented. First the hardware part of the system is configured according to the principle of time domain method, the automatic test for EDFA is realized which by using the GPIB interface. The test efficiency is improved, manual operation is no longer needed and the complexity of EDFA test is reduced. The system software was written in LabVIEW. The software was designed with modular pattern, which is of high cohesion and low coupling. The reusability and extensibility of software is good. It is also easy to maintain and modification： This system could be used for other optical amplifier with only small modification to its hardware and software.
