摘要
某型地空导弹指令接收机是该型导弹中的重要信号处理组合,对弹上信号传输、处理起着较为关键的作用;为确保指令接收机稳定工作,检测其性能指标十分必要;设计基于PXI总线和GPIB总线的指令接收机自动测试系统,对指令接收机的延寿以及维修保障都有重要的意义;实验表明,PXI和GPIB混合总线自动测试系统测试效率高、测试精度高、稳定性好、易维护、人机交互界面友好,能够满足直流电压5V(1A)、6.3V(500mA),中频电源1kHz/127V、20W,环境温度-20℃～+50℃的基本要求,硬件测试及软件调试结果均能满足系统不确定度等一系列要求,具有良好的可扩展性和通用性。
A Command Receiver is an important signal processing component which works for a certain type missile. It means a lot in the process of signal transmission and processing. To ensure that receiver works steadily, as it carries out performance detection, is very necessa- ry. Designing an Automatic Test System for a receiver based on PXI bus and GPIB bus is significant in assessing and extending the life of a certain type of missile. ATS performance is validated in the following respects： greater efficiency based on PXI bus and GPIB bus, accurate test results, excellent stability, easy maintenance, and friendly graphical user interface. Its direct voltage is 5V （1A）. 6.3V （500mA）, medium frequency power supply is I kHz/127V. 20W, ambient humidity is --20℃～＋50℃, both the hardware and software test can sat- isfy the series request such as uncertainty.
