The analysis of dynamic measurements provides numerous challenges that
significantly limit the use of existing calibration facilities and
mathematical methodologies. For instance, dynamic measurement analysis
requires the application of methods from digital signal processing, system
and control theory, and multivariate statistics. The design of digital
filters and the corresponding evaluation of measurement uncertainty for
high-dimensional measurands are particularly challenging. Several
international research projects involving national metrology institutes
(NMIs), academia and industry have developed mathematical, statistical and
technical methodologies for the treatment of dynamic measurements at
NMI level. The aim of the European research project 14SIP08 is the
development of guidelines and software to extend the applicability of those
methodologies to a wider range of users. This paper outlines the required
activities towards a traceability chain for dynamic measurements from NMIs to
industrial applications. A key aspect is the development and provision of a
new open-source software package. The software is freely available, open for
non-commercial distribution, and contains the most important data analysis
tools for dynamic measurements.
