1. A data measurement system comprising:
a plurality of measurement apparatuses;
a data processing apparatus that performs data processing of data sets obtained from the plurality of measurement apparatuses, respectively; and
a transmitter that wirelessly transmits a trigger signal associated with the data processing of the data sets to the plurality of measurement apparatuses, wherein
the trigger signal includes a first group of pulses indicating start timing of the data processing and a second group of pulses indicating end timing of the data processing,
the data processing apparatus obtains the data sets which are measured during a period between the start timing and the end timing, and temporally align the data sets with each other by aligning start timings of the data sets with each other and aligning end timings of the data sets with each other to obtain measurement data from the plurality of measurement apparatuses,
each of the first group of pulses and the second group of pulses includes a first pulse and a second pulse successively transmitted at a prescribed interval,
the first pulse and the second pulse are different from each other in pulse width,
the start timing is timing distant by a first prescribed time period from generation of the first pulse in the first group of pulses or the timing distant by a second prescribed time period from generation of the second pulse in the first group of pulses, and
the end timing is the timing distant by the first prescribed time period from generation of the first pulse in the second group of pulses or the timing distant by the second prescribed time period from generation of the second pulse in the second group of pulses.
