According to the theory of whole-system dynamic accuracy, on the basis of the transfer-chain function and error model of the whole dynamic measuring system, the output error of the system is decomposed by modern signal analysis methods. Then, each unit error is traced to the corresponding inner part of the system according to the characteristics. In order to prove the tracing theory of dynamic measuring error, a simulated simple system was built in this paper. Decomposition and tracing of the output error of this system was performed. The result indicates the correctness and feasibility of this theory.
