Scxi Bus-based Data Acquisition System Developed

This paper mainly discussed the realization and design principle of data acquisition system based on SCXI BUS. This most acquisition of this system is 1MHz, and the precision is 14bits. This system consists of chassis, DAQ module, slotO module, condition module and system soft.Firstly, this paper introduced the structure of SCXI system and it's timing requirement. This part is the base of SCXI system. Secondly it introduced the chassis and slotO. The function of slotO is assisting system in controlling. Then this paper explained how to realize the hardware of DAQ module and condition module. Finally it introduced the design of system software.
