Analysis Source Frame
You can analyze the following frames and patterns.
Frame Start, Error, ID/Data
For the frame format, see “FlexRay Bus Trigger” in chapter 4, “Triggering.”
Bus Setup (Setup)
Source (Source)
Set the analysis source to one of the settings below.
CH1 to CH4*, Math1 to Math4
* You can select CH4 when the key is illuminated.
Bit Rate (Bit Rate)
Select the FlexRay bus signal’s data transfer rate from one of the settings below.
2.5 Mbps, 5 Mbps, 10 Mbps
Bus Channel (Channel)
Select A or B.
Level and Hysteresis (Level/Hysteresis)

Executes auto setup based on the specified sources.
The auto setup feature automatically configures the bit rate, bus channel, level, and hysteresis and triggers on
the start of frame (Frame Start) of the FlexRay bus signal.
You cannot execute auto setup if the source is set to Math1 to Math4.
Decoded Display (Decode)
The colors that are used for the fields in the decoded display are as follows:
Indicator Yellow (Yellow)
Frame ID Light green (Light Green)
Payload Pink (Pink)
Header CRC Light blue (Light Blue)
Cycle Count Orange (Orange)
