Analyzing and Searching CAN Bus Signals (Option)
Analysis Source Frame
The following frames can be analyzed.
Remote, data, error, and overload frames
For the CAN frame format, see “CAN 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 CAN bus signal’s data transfer rate from one of the settings below.
33.3 kbps, 83.3 kbps, 125 kbps, 250 kbps, 500 kbps, 1 Mbps, User Define
If you select User Define, set the transfer rate in the range of 10 kbps to 1 Mbps in 0.1-kbps steps.
Recessive Level (Recessive)
Select the recessive level from one of the settings below. In either setting, the logical value of the recessive level
is 1, and the logical value of the dominant level is 0.
H The recessive level is greater than the dominant level.
L The recessive level is less than the dominant level.
Sample Point (Sample Point)
Set the reference that will be used to determine the bus level (recessive or dominant) in the range of 18.8 to
90.6% in 3.1% steps.
Level (Level) and Hysteresis (Hys)
These items are the same as those of the edge search.
Auto Setup (Auto Setup)
Executes auto setup based on the specified sources.
The auto setup feature automatically configures the bit rate, recessive level, sample point, level, and hysteresis
and triggers on the start of frame (SOF) of the CAN 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:
Arbitration Light green (Light Green)
Control Pink (Pink)
Data Cyan (Cyan)
CRC Light blue (Light Blue)
Error bit, field in which the error occurred,
frame, error frame
Red (Red)
Overload frame Green (Green)
Frame background Gray (Gray)
Stuff bits Gray (Gray) fill
