Abstract :
With the development of testing bus technology, PXI/VXI bus is implemented in navigation signal simulator. The automatic test software mostly communicates with the simulator by using direct I/O. Due to a lack of uniform standards, it´s not convenient for function upgrading and extension. A navigation signal simulator solution based on LXI(LAN eXtensions for Instrumentation) bus is proposed. Through the analysis of technique features of LXI bus standard, the hardware architecture of navigation signal simulator is designed. Meanwhile, the implementation of VXI-11-based remote control is mainly discussed. The simulator is controlled by driver interface in line with IVI (Interchangeable Virtual Instrumentation) specification to unify software programming interfaces of different simulators, so ATS (Automatic Test System) only needs to change the simulator driver after simulator upgrading or replacement which can greatly improve the reusability of automatic test software.
