数字T/R组件的自动测试系统设计与实现

Design and Implementation of Automatic Test System for Digital T/R Modules

数字T/R组件是数字阵列系统的重要组成部分,针对数字T/R组件测试指标复杂、数据处理繁多等测试需求,设计开发了一种自动测试系统。该系统通过GPIB总线控制测试仪器,通过网口控制光纤采集板实现T/R组件指标的全自动测试。介绍了测试系统的硬件设计,软件功能开发,系统校验与指标测试。该测试系统在实际应用中缩短了测试时间,有效提高了研制生产效率。

Digital T/R modules is an important part of the digital array system.An automatic test system is designed and developed in this paper to meet the test requirements of digital T/R modules such as complex test indexs and numerous data processing.The system controls the test instrument through the GPIB bus and optical fiber acquisition board through the network port to realize the automatic test of T/R modules.This paper introduces the hardware design,software function development,system calibration and index test.The test system can shorten the test time and improve the production efficiency.
