On the basis of the standard IEEE 1588, the PC cooperating in the Distributed Measurement System can work on synchronized modality. Nevertheless, the hardware and software architecture of the path involved in the communication PC-Measurement Instrument (MI) can delay the commands. The research aims to investigate about the time delay occurring in the communication between the PC and the MI. Two different aspects are taken into account: (i) the characterization of the hardware connection PC-MI offering the minimum delay, and (ii) the criteria to modify and to set up the software to reduce the delay occurring in the processing steps performed into the PC. In particular, experimental results are performed with (i) different hardware connections PC-Digital Storage Oscilloscope (DSO), and (ii) different setting up of the Linux Operating System. The experimental tests highlight that delay characterized by mean value equal to 0.46μs and standard deviation of 10.2 ns can be achieved.
