Abstract In this paper, an innovative measure architecture aimed to generate synchronous and correct data is presented. This measure architecture takes into account the most common needs in the field of static and dynamic behaviour of civil infrastructures (for instance, execute proper Operational Modal Analysis, have a solid decoupling of acceleration signals against temperature, capability to use structure- specific set of sensors, …) and propose a possible solution which is already proven in the field. © 2022 The Authors.
