In the current popular bus connection mode, the VXI bus form is widely used by automated test systems. The structure of the virtual instrument test system based on the GPIB VXI control mode is discussed. The composition scheme of the virtual bus test system for the hybrid bus is studied. The master computer Through the GPIB bus to connect to the bus connected to the VXI bus instruments and GPIB bus instrument control, this solution to improve system flexibility and reduce system costs, the system has a strong versatility and scalability .
