采用 GPIB 接口的多路耦合器自动测试技术

摘要

为满足多路耦合器自动测试需求，论文选择 GPIB 接口技术搭建自动测试平台，采用 AT89S51和 FT232RL芯片设计制作了 GPIB 卡，采用 VC ＋＋编程语言设计了自动测试软件，通过电脑连接并控制矢量网络分析仪，最终实现了对多路耦合器相关参数的自动测试。%In order to meet the needs of automatic testing of multicoupler ,this paper chooses GPIB interface technology to build automatic testing platform ,uses AT89S51 and FT232RL chip to design the GPIB card ,uses VC + + programming language to design the automatic test software .To connect and control the VNA through the computer ,the automatic test of related parameters on the multicoupler is realized .
