【Abstract】 The main points of the design of a high speed (3MSPS) and high resolution(12 bit) data acquisition board, including the multi channel converter, high speed ADC (AD 1672), data buffer memory, interruption expansion and computer interface, are described in this paper. It can be inserted to the expansion slot of a computer forming a compatible data acquisition system with a large buffer memory and a high ratio of function to cost.更多还原
