Master Timebase and Reference Clock Sharing

[VS_03]

Hello community ,

are the benefits of a master timebase or refernce clock connected to the device series? (For example, E series devices 
can only share via master timebases, and M series devices can only share reference clock signals.) My task should automaticly 
detect available kind of synchronization and use it. The master (output) uses Master Timebase. The multiple capture cards will 
synchonized through the RTSI-line. My idea is to get ProductCategory via DAQmx Device and depending on case select Master 
Timebase or Reference Clock. Are there better options ?

Is it correct that synchronization with reference clock is synchronized via a PLL with the master and Master Timebase 
uses directly the clock of master?

Hi,

you got everything correct. Here is a link to a document that explains clocks more detailed:

The approach with the case structure, to chose the right kind of synch-rechnique is a good idea for your application.
