FlexRay Triggering
FlexRay triggering is easily accessible in a variety of ways. The TD and TDP options add an additional Serial
selection to the Trigger Type in the Trigger dialog. These dialogs are shared by all the low-speed serial protocols
LeCroy offers. This is why all serial trigger selections are grouped in a common section with nearly identical
selection and setup procedures (if installed on the oscilloscope). These dialogs are conveniently accessed with
just one or two touches of the screen.
If you are not familiar with or are just learning about FlexRay, begin by using the simplest trigger conditions (TSS,
or Frame ID). Then, experiment with an ID + Count “Equal” to a specific value. Then, try a conditional ID + Cycle
Count trigger (ID “Greater Than” or “In Range”).
Accessing the FlexRay Trigger
The FlexRay serial trigger is accessed from the oscilloscope trigger dialog. This dialog can be accessed as
follows:
1. Touch
the Trigger Descriptor Box in the lower right
corner of the oscilloscope display.
Or
Touch Trigger ÆTrigger Setup on the Menu Bar.
2. Touch Serial in the Type selection area.
3. Select the FlexRay trigger. The menu automatically
changes to a different tab on the Trigger dialog. The
tab is named after the serial trigger selected.

multiple serial data trigger options installed.
