Stable triggering- Important stuff about triggering

Make sure that little arrow is above what u need !! Else u can't trigger it so well!! 

Use this nob :

Now when you try and trigger multiple channels together remember these things - 

1. Only one channel can be selected for the dso TDS 2024B as the source of trigger . What should you pick? Pick that trigger which gives Max date vs time. For example - 

I have set yellow channel as my trigger. Observe that the white arrow on top if the screen actually tells you where the capture is going to start from. 

Once all this is set. The other channels follow this trigger ! 

Yay! That's all the configurations needed for this setup !
