Abstract :
In this paper, three kinds of hardware design schemes for virtual oscilloscope is introduced firstly. Then the measurement and parameter calculation methods are depicted, and correlative error analysis is executed. In virtual instrument design, how to ascertain correct hardware is a precondition of all other works. This paper, using theoretic analysis and example demonstration to summarize the evaluating methods of DAQ cards, is a good reference to engineering applications.
