Synchronization Options between VX1000 Interfaces in CANape
The Support Note Synchronization Options between VX1000 Interfaces in CANape describes the different synchronization options for VX1000 interfaces.
All measurement and ECU interfaces use their own time stamps for the measured data. Because of the nature of these clocks, the time stamps are - more or less - influenced by drift and jitter.
Without synchronization, the time stamps of different clock sources tend to drift. This drift destroys the time correlation between signals created by different clock sources/interfaces. To precisely compare signals in long time measurements it is necessary to use a synchronization mechanism to reduce or eliminate the drift effects. Jitter effects can’t be eliminated.
This document describes the different synchronization options for VX1000 interfaces, the advantages and disadvantages of these options and which is most suitable in which use case.
In the second part, the synchronization options are explained step by step. Furthermore this document explains which VX1000 DAQ “Timestamp” should be used and how it is configured.
