5 Press the Errors softkey, and use the Entry knob to select the error type:
• All Errors
• Code Error (NRZ) — NRZ decoding errors only.
• TSS Violation — transmission start sequence violation.
• Header CRC Error — cyclic redundancy check error in the header.
• Frame CRC Error — cyclic redundancy check error in the frame.
• Frame End Sequence Error — indicates that the FES has been violated.
• Boundary Violation — frame received overlaps slot boundaries (synchronous
monitoring mode only).
• Network Idle Time Violation — frame received with NIT (synchronous monitoring
mode only).
• Symbol Window Violation — frame received within symbol window, or symbol
received outside of symbol window (synchronous monitoring mode only).
• Slot Overbooked Error — two or more communication elements have been
received within one slot.
• Null Frame Error — null frame received within dynamic segment (synchronous
monitoring mode only).
• Sync or Startup Error — sync bit or startup bit set within dynamic segment
(synchronous monitoring mode only).
• Frame ID Error — mismatch between internal and received slot ID (synchronous
monitoring mode only).
• Cycle Count Error — mismatch between internal and received cycle counter
(synchronous monitoring mode only).
• Static Payload Length Error — unexpected payload length within static segment
(synchronous monitoring mode only).
NOTE
Since FlexRay errors 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 an error to occur. You may need to adjust trigger holdoff
to see a particular error when multiple errors exist.
