Search tips

apple banana
Find rows that contain at least one of the two words.

+apple +juice
Find rows that contain both words.

+apple macintosh
Find rows that contain the word 'apple', but rank rows higher if they also contain 'macintosh'.

+apple -macintosh
Find rows that contain the word 'apple' but not 'macintosh'.

+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

+apple +(>turnover >strudel)
Find rows that contain the words 'apple' and 'turnover', or 'apple' and 'strudel' (in any order), but rank 'apple turnover' higher than 'apple strudel'.

apple*
Find rows that contain words such as 'apple', 'apples', 'applesauce', or 'applet'.

"some words"
Find rows that contain the exact phrase 'some words' (for example, rows that contain 'some words of wisdom' but not "some noise words").

Synchronization Options between VX1000 Interfaces in CANape

Last updated: 2019-09-26
Support Note:

The Support Note Synchronization Options between VX1000 Interfaces in CANape describes the different synchronization options for VX1000 interfaces.

Overview:

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.
