Analysis of ATE Measurability Using Information Flow Model
Since many test equipments can't be calibrated conveniently, this paper proposed a new concept named measurability to solve the problem. The measurability is defined, and its indexes are given in detail. Selected from the models of testability, the information flow model is used to analyze the ATE (automatic test equipment) measurability. The correlative matrix of information flow model is decided according to the trace chain. Finally, a practical example is given to show the analysis process.
