The first problem is interface and communication. The second problem is man-machine interface and data processing. The computers collect various measurement data by GPIBbus, realize program controlled and parameter setup by measurement software developed by ourselves, auto-process measure data and produce measurement report. Key words: Virtual apparatus; GPIB bus; IEEE488 standard; Vb.net2003
