VXI总线技术在空间有效载荷自动测试设备中的应用

Application of VXI bus technology in ATE for space net-load

采用VXI总线技术组建的自动测试设备包括智能接口、由VXI总线模块仪器组成的数据采集系统和以VEE为开发环境的自动测试软件。智能接口成功地解决了对测试对象提供的检测信号的相互隔离 ;VXI总线模块仪器的使用大大地提高了整个自动测试设备的硬件可靠性 ;使用VEE开发自动测试软件 ,降低了软件开发的复杂程度 ,缩短了开发周期 ,保证了自动测试软件可靠性。这套自动测试设备实现了对空间有效载荷的在线自动测试 。

This set of ATE(Auto Test Equipment) based on VXI bus technology includes an intelligent interface, a data acquisition system of VXI bus module devices and an auto test software developed via VEE. The intelligent interface isolates the test signals provided by DUT(device under test) successfully. The use of VXI bus module devices improves the ATE hardware reliability, while the use of VEE reduces the software development complexity,shortens its period and keeps the auto test software in guarantee. This set of ATE accomplishes online measurement and test for the space net-load automatically, and provides various reliable data to test the functions of the space net-load.
