TLDR
In this article, the synchronization of the phase between measurement devices that do not share a single clock for the respective sampling of the signals thereof is carried out by time tagging of signal samples in time blocks followed by an adjustment of phase values of components of interest of signals in the grouped time blocks, such that said values refer to time references which are common between the measuring devices.Abstract:
According to the invention, the time synchronization of the phase between measurement devices that do not share a single clock for the respective sampling of the signals thereof is carried out by the time tagging of signal samples in time blocks followed by an adjustment of the phase values of components of interest of the signals in the grouped time blocks, such that said values refer to time references which are common between the measuring devices. The tagging is carried out using a synchronization signal that is available for the measuring devices, and that is completed by means of counting values provided by a counter operated by a reference clock for each measurement device.read more
