微波开关自动测试系统设计

Design of Automatic Test System for Microwave Switch

针对当前微波开关指标测试流程复杂、测试方法自动化程度低问题,提出了一套集指标测试、数据采集和数据管理功能于一体的自动化测试系统;该系统基于微波开关生产及试验环节的实际使用需求,通过软件平台实现对通用测量仪器及遥控遥测设备、射频开关矩阵等设备的自动化控制,单次可满足最多16个微波开关的同步测试,可实现同轴型和波导型两类开关的S参数、切换时间、门限电压、接触电阻、跑荷等总计18种指标参数的测试和试验数据管理,达到了测试效率和试验质量的双提升。

To address the problems of complicated testing process and low automation level in current microwave switch evaluation methods,an automated testing system is proposed to integrate the index testing,data acquisition,and data management function.This system is based on the practical needs of microwave switch production and testing,and achieves the automate controls of universal measuring instruments,remote control and telemetry equipment,and radio frequency switch matrices on the software platform,simultaneously meeting a maximum of 16 microwave switches at a time,it can achieve the testing and experimental management,including the S parameter,switching time,threshold voltage,contact resistance,and running load for the coaxial and waveguide type switches,it improves the testing efficiency and experimental quality of data management.
