Method and system for time synchronization of phase of signals from respective measurement devices

A system for time synchronization of phase of signals from respective measurement devices, the system comprising:

• for each measurement device, a phase measurement unit comprising:
• a receiver that receives a synchronization signal available to each phase measurement unit;
• a clock that produces a reference clock signal having a higher rate than the synchronization signal;
• and
• a processing unit;
• and
• for all the measurement devices, a phase processing unit comprising a processing unit;
• the processing unit of each phase measurement unit being configured to receive the signal from the corresponding measurement device, receive the synchronization signal, receive the reference clock signal, provide a counter operating in response to the reference clock signal to produce count values, complete the synchronization signal with the count values provided by the counter, select at least one time block having a finite number of samples in the signal from the measurement device, establish time locations of at least two samples of each time block with the completed synchronization signal, estimate a phase value and a temporal characteristic of at least one component of the signal from the measurement device in each time block, and produce data representative of the at least one component, the phase value, the temporal characteristic, and the time locations;
• the processing unit of one of each phase measurement unit and the phase processing unit being configured to assign a time tag derived from the completed synchronization signal to each time block, the time tag forming part of the data relative to each time block;
• and
• the processing unit of the phase processing unit being configured to regroup the data relative to the time blocks having like time tags under same time tags used as common time references, and calculate 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.
