【Abstract】 The paper consists of two parts, the first subject is the research on high precision charge calibrator, the other one is the measurement and application of the dynamic testing ASICs.In the first part, the virtual high precision calibrator communicating with computer through parallel port is researched based on the detailed analysis of virtual instrument technology and domestic and foreign technology of charge calibrator. Based on the theory of charge calibration and sample and reconstruction of frequency limited signal, the scheme of adopting direct digital synthesizing technology and technology of computer is put forward in the paper. The design of hardware and software is described in detail, the error of the outputs signals of the high precision charge calibrator has been analyzed in theory. The experiment result shows that the scheme is correct and feasible, and the quality of the low-cost high precision charge calibrator has exceed the level of like product both at home and abroad, which has meet the requirement of this subject. The research on high precision charge calibrator is significant and valuable. In the second part, the research background and function of dynamic testing ASIC HB0201 and HB0202 is introduced. An analog-digital, computer-interactive method of testing and measuring is proposed, measuring scheme of ASIC products is built. Finally, the paper simple introduces the application of HB0201 and HB0202 in memorized testing system.更多还原
