基于PXI总线的甚高频全向信标模拟器设计

Design of VHF Omnidirectional Range Simulator Based on PXI Bus

甚高频全向信标模拟器可用于甚高频全向信标机载设备的检测与维修。为方便携带与系统集成,该文按照合成仪器设计思想,采用标准总线与软件无线电的开放式体系架构,设计出一种基于PXI总线、便于集成、小型化的甚高频全向信标模拟器。该模拟器可方便应用于机载VOR设备的现场维修测试,特别是外场维修检测,提高设备的外场保障能力。

VHF omnidirectional range simulator can be used to test and maintain airborne equipment of VHF omnidirectional beacon.In order to be easily carried out and integrated into systems,this article comes up with a VHF omnidirectional range simulator which is miniaturized,easily carried and based on PXI bus.This simulator can be applied to the VOR navigation equipment in on-site maintenance testing especially in out-field maintenance testing,which can enhance the out-field maintenance capability of VOR equipment.
