Automatic test system of virtual radio based on VI n bus plum Mann Liu Yunjiang Yin Xiaochuan Air Force Engineering University A virtual radio automatic test system based on VxI bus is studied. The structure design of the system is introduced, and the realization method of the software and hardware of the system is analyzed emphatically And the key technology in design. It is proved that the system has strong flexibility and expansibility.

The lamp S test system has the ability of excitation, measurement, channel switching and data processing. The external master computer is the control center of the whole measurement and control platform. The functions of instrument self checking, reset, test flow control, data acquisition and data processing are completed. The core of measurement and control platform is vxI bus. Communication between main control computer and vXI test equipment is completed by PcI - MxI - vXI bus. In the RF source, the GPIB control interface is used to make up for the lack of VXI instruments in this regard. VxI bus is a relatively mature and advanced instrument bus, and com
