VXIbus is an excellent bus used in the instrumentation and the automatic test systems, and the arbitrary waveform generator module based on VXIbus is an important module in the automatic test systems based on VXIbus. In this paper, the design principle and realization method of the arbitrary waveform generator based on VXI was put forward, and its VXIbus register-based interface and realizable functions were presented, its hardware and instrument driver software were designed, and furthermore the arbitrary waveform generator module was developed. The experiment shows that the developed arbitrary waveform generator based on VXIbus can generate the normal waveform and the arbitrary waveform with high accuracy.
