用于高速网络分析仪校准的自动测试系统设计

高速网络分析仪是射频生产测试中非常重要的仪器,对网络分析仪的定期校准用于检查其性能是否满足使用要求。本文提出了一种用于高速网络分析仪校准的自动测试系统的实现方案。该系统以计算机为控制核心,通过GPIB总线将各仪表进行互连,并且使用VC作为校准应用程序的开发工具。通过程序控制总线上的仪表作业,按要求进行测试和数据处理工作,最终生成校准证书,实现了网络分析仪的自动校准。该系统节省了人力和时间,显著地提高了工作效率。

Automated test system for high-speed network analyzer calibration

High-speed network analyzer is very important in RF manufacture and test,and it's performance is checked by periodic calibration.A high-speed network analyzer for the calibration of automatic test system program is introduced.The system is computer-controlled core through GPIB bus interconnecting the instrument,and useing VC as a calibration application development tools.Through process controlled instrumentation bus operations,according to the requirements for testing and data-processing jobs and this will generate calibration certificate,achieving to automatic calibration.The system saves manpower and time,significantly improved the efficiency.
