【Abstract】 <Abstrcat> It introduces the design of multichanel pulse amplitude analyzer which adopts the method of two step linearity discharge. In the system, the core of the conversion and control unit is achieved in the spantar ⅡE xc2s100e of Xilinx corporation by programming with the VHDL. The high-speed transport of the data to PC adopts the port chip of USB2.0. The system expedites the aped of the conversion and decreases the measuring dead time. It improves the differential none-linearity and integral none-linearity. So it advance the accuracy and the stability of the system.更多还原
