Methods for use in a measurement system. Some embodiments comprise at least one sensor unit and a control unit, wherein the at least one sensor unit is configured to detect a physical quantity and to form a sensor data signal. The method comprises, at the control unit, receiving a data receive signal from the sensor unit, and interpreting the data receive signal to be one of at least the sensor data signal and another data signal, wherein the interpreting is based on an attribute information intrinsic to the data receive signal. Furthermore, there is a sensor unit for use in measurement data acquisition, an apparatus configured to control a measurement data acquisition, a measurement system for use in measurement data acquisition, and a medium incorporating a sequence of operation steps that, when executed, perform a method for use in a measurement system for data acquisition.

The trigger signal includes a first group of pulsesindicating start timing and a second group of pulses indicating end timing of data processing. The data processing apparatus processes measurement data sets measured during a period between the start timing and the end timing by temporally align the measurement data sets with each other. Each of the first group of pulses and the second group of pulses includes a first pulse and a second pulse different in pulse width from each other. The start timing is timing distant by a first time period from the first pulse or timing distant by a second time period from the second pulse in the first group of pulses, and the end timing is timing distant by the first time period from the first pulse or timing distant by the second time period from the second pulse in the second group of pulses.
