When you are configuring a trigger for your acquistion with niScope, you are really configuring a reference or stop trigger. This trigger has a reference position with relation to the record that you are acquiring. By default, the trigger occurs at the 50% mark in the record so that you have half of your data before the trigger and the other half after the trigger. Where the trigger occurs can easily be changed in software with the reference position input in the niScope Configure Horizontal VI.
Now that we have an idea of what the reference or stop trigger is, in the synchronization example, the master is exporting its stop trigger to share it with the slave NI-5112. This way both boards are triggered at the same time without having to provide the same trig
ger condition to both boards simultaneously.
Hope that clears some stuff up.
