FlexRay Triggering and Serial Decode
Because specific FlexRay frames may occur infrequently, it may be helpful to press the
N O T E
[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.

Triggering on FlexRay Errors

1 Press [Trigger].
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob
3 Press the Trigger softkey; then, turn the Entry knob to select Error.
4 Press the Errors softkey; then, select the error type:

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.
to select the serial bus (Serial 1 or Serial 2) on which the FlexRay
signals are being decoded.
All Errors
