Chapter 3: Using the Logic Analyzer in Timing or State Mode
Cross-Triggering
Cross-Triggering
An instrument must be armed before it can look for a trigger. By
default, instruments are set to be armed immediately when you Run
the measurement.
However, you can set an analyzer instrument to be armed by another
instrument (in a different slot or frame).

System and Intermodule).
2. In the Intermodule window, select the desired instrument icon and arm it
from the Group Run.
3. Select the next instrument icon and arm it from the first instrument.
