Advanced Triggering, Search & Navigation, and Segmented Acquisition Labs
Lab #14: Triggering on Logic Patterns using the MSO’s Digital Channels
In this lab you will learn how to use the scope’s digital channels of
acquisition (MSO), and then set up the scope to trigger on a specific
Boolean pattern combination. Note that to complete this lab your scope
must either be an MSO model, or a DSO model that has been upgraded
with the MSO option (Option MSO). You can verify the installed options on
your oscilloscope at
