Teledyne LeCroy FlexRay Trigger, Decode and Physical Layer Test - Manual (Page 12)

Error Trigger Setup
This set of checkboxes are shown if Error is selected as
the trigger type. The errors are broken in to 2 categories,
Protocol Errors and CRC Errors.
Protocol Errors:
• Frame Start Sequence (FSS)
• Byte Start Sequence (BSS)
• Frame End Sequence (FES)
CRC Errors:
• Header
CRC
• Payload
CRC
• The correct channel must be selected when triggering
on CRC errors
• Check or uncheck each one, as desired, to include or
not include that specific type of error in the trigger.
• For convenience Select and Deselect All buttons are
available when using Error triggering.
• Detailed description of the Error Triggers is found in
Appendix C.
FlexRay Decoding
FlexRay decoding tools are easily accessible in a variety of ways. The D, TD and TDP options add a new set of
dialogs for Decode setup. These dialogs are shared by all the low-speed serial protocols that LeCroy offers, so all
serial trigger and serial decoding selections are grouped in a common selection with nearly identical selection and
setup. These dialogs are conveniently accessed with just one or two touches of the screen.
Decode and Decode Setup
These dialogs provide the ability to set the oscilloscope up for FlexRay decoding, with display of the protocol data
overlaid on the signal. They also allow quick and easy access to oscilloscope zooming, searching, table display,
and table export.
The serial decode and decode setup dialogs are accessed in the following ways:
1. Touch Analysis Æ Serial Decode from the menu bar. The Serial
Decode Summary dialog is shown which provides access to
Decode Setup.
2. Touch the Channel or Memory Descriptor Box to open the
respective dialog box, and touch the Decode button on the bottom
toolbar.
