FlexRay Triggering and Serial Decode
To trigger on a particular cycle, set the Cycle Repetition factor to 64 and use
the cycle base factor to choose a cycle.
To trigger all (any) cycles, set the Cycle Repetition factor to All. The scope will
trigger on any and all cycles.
Triggering on FlexRay Errors
1 Press [Trigger] .
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob to
select the serial bus (Serial 1 or Serial 2) on which the FlexRay signals are being
decoded.
3 Press the Trigger softkey; then, turn the Entry knob to select Error .
4 Press the Errors softkey; then, select the error type:
• All Errors
• Header CRC Error — cyclic redundancy check error in the header.
• Frame CRC Error — cyclic redundancy check error in the frame.
Triggering on FlexRay Events
1 Press [Trigger] .
NOTE
Because specific FlexRay frames may occur infrequently, it may be helpful to press the
[Mode/Coupling] key, then press the Mode softkey to set the trigger mode from Auto to
Normal . This prevents the oscilloscope from Auto triggering while waiting for a particular
frame and cycle combination.
NOTE
Because FlexRay errors occur infrequently it may be helpful to set the oscilloscope to press
the [Mode/Coupling] key, then press the Mode softkey to set the trigger mode from Auto to
Normal . This prevents the oscilloscope from Auto triggering while waiting for an error to
occur. You may need to adjust trigger holdoff to see a particular error when multiple errors
exist.
