Summary:It is proposed a method for providing synchronization in a data acquisition system including a plurality of acquisition units. A given acquisition unit of the plurality carries out the following steps: receiving a packet from another device of the data acquisition system; extracting a synchronization accuracy information and a reference clock information from the received packet; obtaining a first reference clock as a function of the extracted reference clock information; if the extracted synchronization accuracy information indicates a better synchronization accuracy than a current synchronization accuracy information associated to the given acquisition unit: taking the obtained first reference clock as a selected reference clock and updating the current synchronization accuracy information to indicate a lower synchronization accuracy than the extracted synchronization accuracy information.
