基于GPIB的多通道光功率计自动校准系统设计

Design of optical multiport power meter automatic calibration system based on GPIB

多通道光功率计是光纤通信网络中的一种测试仪器,为保证测试的准确性,必须对多通道光功率计进行规范的校准。针对传统人工手动校准效率低、易出错的缺点,利用VS2012开发工具,设计和实现了一种基于GPIB的多通道光功率计自动校准系统。详细介绍了系统硬件组成及连接、系统软件设计、自动校准方法与步骤,并给出了校准结果。

Optical multiport power meter is widely used in measurements of the optical fiber communication network. To insure the accuracy of measurements, the optical multiport power meter must be corrected according to calibration standard. To overcome the inefficiency and inaccuracy of the traditional manual operation method,an optical multiport power meter automatic calibration system is designed and implemented using Microsoft Visual Studio 2012 programming environment based on GPIB in the paper. It introduces system hardware composition and connection, software design, automatic calibration method and procedure, and shows the results of calibration.
