TYPE A EVALUATION OF UNCERTAINTY DUE TO SYSTEMATIC EFFECTS IN DIGITAL OSCILLOSCOPES
Filippo Attivissimo, Andrea Cataldo, Laura Fabbiano, Nicola Giaquinto
Abstract:
The paper presents a type A (experimental) evaluation of the uncertainty due to systematic effects. After a brief discussion about the general problem of choosing a proper mathematical representation for systematic effects in the context of uncertainty evaluation, a pragmatic approach, based on the familiar random variable theory and the ISO 5725 norm is proposed. The approach is called "inter-instrument experiment", on the analogy of the "inter-laboratory experiment" of the ISO 5725. Preliminary experimental results, relevant to commercial digital oscilloscopes, are presented and discussed.
