List Display (List)
The list displays the following items.
No.
Analysis number. Negative numbers are assigned to frames before the and positive numbers
are assigned to frames after the trigger position.*
The instrument can display the analysis results for up to 5000 frames in the range of −5000 to
5000. Pressing the RESET key highlights frame number zero.
Time(ms)
Displays the time from the trigger position* to the start of the frame in milliseconds.
S/D
Displays the frame type.
S: Static Frame, D: Dynamic Frame
IND
Displays the states of the four header segment indicators in the following order using bit
patterns.
Payload preamble indicator, Null frame indicator, Sync frame indicator, Startup frame indicator
ID
Displays the 11-bit frame ID in decimal notation.
Len
Displays the data length of the payload segment in decimal notation.
CC
Displays the cycle-count value in decimal notation.
Data
Displays Data 0 to Data n of the payload segment (n = byte 0 to 253) in hexadecimal notation.
Information
Displays the following error information. If multiple errors are detected in one frame, the
instrument displays the error with the highest precedence. The errors are listed below in order
of precedence with the highest precedence error first.
BSS Error: BSS not detected, FES Error: FES not detected, Header CRCError: Incorrect
header CRC, CRC Error: incorrect CRC
* If
is set to OFF, they are based on the trigger point.
Search Setup (Search)
Search Type (Mode)
Select the FlexRay bus signal search type from one of the settings below.
• Frame Start: Searches for the starting position of the frame
• Error: Searches for errors
• ID/Data: Searches for the position where the AND condition of the ID bit pattern and Data pattern is met
If you set the type to Error or ID/Data, set the search conditions.
The method to set search conditions is the same as that for the trigger conditions of the FlexRay bus trigger.
Executing a Search (Search)
The instrument searches for locations where the specified search conditions are met. Then, the instrument
displays the frame corresponding to the specified detected point number (Pattern No) expanded in the zoom
window.
Detected Points
The detected points are the same as the trigger points.
Jumping to the Specified Field (Field Jump)
You can move the zoom position to the start of the following fields in the frame corresponding to the specified
detected point number.
ID, Payload Length, Header CRC, Cycle Count, CRC
