5 Press the Frames softkey to access the FlexRay Frame Trigger Menu.
6 Press the Frame ID softkey, and use the Entry knob to select the frame ID value from
All or 1 to 2047.
7 Press the Frame Type softkey to select the frame type:
• All Frames
• Startup Frames
• NULL Frames
• Sync Frames
• Normal Frames
• NOT Startup Frames
• NOT NULL Frames
• NOT Sync Frames
8 Press the Cyc Ct Rep softkey, and use the Entry knob to select the cycle count
repetition factor (2, 4, 8, 16, 32, or 64, or All).
9 Press the Cyc Ct Bas softkey, and use the Entry knob to select the cycle count base
factor from 0 through the Cyc Ct Rep factor minus 1.
For example, with a base factor of 1 and a repetition factor of 16, the oscilloscope
triggers on cycles 1, 17, 33, 49, and 65.
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.
NOTE
Because specific FlexRay frames may occur infrequently, it may be helpful to set the
oscilloscope to Normal trigger mode instead of Auto trigger mode. This prevents the
oscilloscope from Auto triggering while waiting for a particular frame and cycle
combination.
