A method for time synchronization of phase of signals from respective measurement devices, the method comprising the steps of: for each measurement device: receiving a synchronization signal available to each measurement device; producing a reference clock signal having a higher rate than the synchronization signal; operating a counter in response to the reference clock signal to produce count values; completing the synchronization signal with the count values provided by the counter; selecting at least one time block having a finite number of samples in the signal from the measurement device; establishing time locations of at least two samples of each time block with the completed synchronization signal; estimating a phase value and a temporal characteristic of at least one component of the signal from the measurement device in each time block; assigning a time tag derived from the completed synchronization signal to each time block; and producing data representative of the at least one component, the phase value, the temporal characteristic, the time locations and the time tag for each time block; and for all the measurement devices: regrouping the data relative to the time blocks having like time tags according to a predetermined similarity criterion under same time tags used as common time references; and calculating new phase values of the at least one component in the time blocks according to the respective common time references and the corresponding time locations for the time synchronization of phase of the signals from the measurement devices. for each measurement device: receiving a synchronization signal available to each measurement device; producing a reference clock signal having a higher rate than the synchronization signal; operating a counter in response to the reference clock signal to produce count values; completing the synchronization signal with the count values provided by the counter; selecting at least one time block having a finite number of samples in the signal from the measurement device; establishing time locations of at least two samples of each time block with the completed synchronization signal; estimating a phase value and a temporal characteristic of at least one component of the signal from the measurement device in each time block; assigning a time tag derived from the completed synchronization signal to each time block; and producing data representative of the at least one component, the phase value, the temporal characteristic, the time locations and the time tag for each time block; and for all the measurement devices: regrouping the data relative to the time blocks having like time tags according to a predetermined similarity criterion under same time tags used as common time references; and calculating new phase values of the at least one component in the time blocks according to the respective common time references and the corresponding time locations for the time synchronization of phase of the signals from the measurement devices. receiving a synchronization signal available to each measurement device; producing a reference clock signal having a higher rate than the synchronization signal; operating a counter in response to the reference clock signal to produce count values; completing the synchronization signal with the count values provided by the counter; selecting at least one time block having a finite number of samples in the signal from the measurement device; establishing time locations of at least two samples of each time block with the completed synchronization signal; estimating a phase value and a temporal characteristic of at least one component of the signal from the measurement device in each time block; assigning a time tag derived from the completed synchronization signal to each time block; and producing data representative of the at least one component, the phase value, the temporal characteristic, the time locations and the time tag for each time block; and for all the measurement devices: regrouping the data relative to the time blocks having like time tags according to a predetermined similarity criterion under same time tags used as common time references; and calculating new phase values of the at least one component in the time blocks according to the respective common time references and the corresponding time locations for the time synchronization of phase of the signals from the measurement devices. regrouping the data relative to the time blocks having like time tags according to a predetermined similarity criterion under same time tags used as common time references; and calculating new phase values of the at least one component in the time blocks according to the respective common time references and the corresponding time locations for the time synchronization of phase of the signals from the measurement devices.
