The invention relates to a method for wire bound, high precision, temporal synchronization of measured value acquisition in a measurement system designed as a space coordinate measurement apparatus having a plurality of measurement sub-units with signaling of a time for triggering the measured value acquisition by means of a trigger signal and with the respective acquisition and intermediate storage of a measured value in the measurement sub-unit at the time determined by the trigger signal. Each acquisition of the measured value is carried out in the measurement sub-units in a time quantified manner with a local timing signal of the measurement sub-unit. A phase synchronization of the local timing signals of the measurement sub-units is then carried out using a synchronization signal in order to ensure simultaneity of the acquisition of the measured value in the measurement sub-units with a temporal uncertainty which does not exceed a phase jitter of the synchronization, and which is in any case less than 90% of a period duration of the local timing signal.
