16.8 CAN FD Trigger and Serial Decode
This section covers triggering and decoding CAN FD signals. Please read the following
for more details: " CAN FD Signal Settings", " CAN FD Trigger" and " CAN FD Serial
Decode".
16.8.1 CAN FD Signal Settings
Connect the CAN FD signal to the oscilloscope, and then set the threshold level of the
signal. The process of specifying the source and threshold is similar to " I2C Signal
Settings".
In BusConfig menu of trigger and decode, the nominal baud rate can be set to: 10 kb/s,
25 kb/s, 50 kb/s, 100 kb/s, 250 kb/s, 1 Mb/s or Custom. The data baud rate can be set
to: 500 kb/s, 1 Mb/s, 2 Mb/s, 5 Mb/s, 8 Mb/s, 10 Mb/s or Custom.
The method of copying settings is the same as I2C signal settings. See " I2C Signal
Settings" for details.
16.8.2 CAN FD Trigger
Touch Trigger Setting in the CAN FD trigger dialog box to set the trigger conditions:
A. Frame Type: Both, CAN, CAN FD
B. When the "Frame Type" is CAN FD, turn on or off ISO
C. When the "Frame Type" is CAN FD, set the BRS (Bit Rate
Switch) to Both, Normal or FD
D. Trigger Condition: Start, Remote, ID, ID + Data, Error
E. Return to previous menu
Trigger Condition
•
Start— The oscilloscope triggers at the beginning of the
frame.
•
Remote— The oscilloscope triggers on a remote frame
with a specified ID. ID, ID Bits (11-bit or 29-bit) and Curr ID
Byte (1st, 2nd, 3rd, or 4th byte) can be set. Curr ID Byte is
used to specify the byte to be adjusted when using the
universal knob.
•
ID— The oscilloscope triggers on the data frame that matches the specified ID. ID, ID
Bits (11-bit or 29-bit), and Curr ID Byte (1st, 2nd, 3rd, or 4th byte) can be set.
