16.5 CAN Trigger and Serial Decode

This section covers triggering and decoding CAN signals. Please read the following for
more details: " CAN Signal Settings", " CAN Trigger" and " CAN Serial Decode".

16.5.1 CAN Signal Settings

Connect the CAN_H and CAN_L signals to the oscilloscope, set the mapping relation
between channels and signals, and then set the threshold level of each signal. The
process of specifying the source and threshold is similar to " I2C Signal Settings".
In BusConfig menu of trigger and decode, baud rate can be set to: 5 kb/s, 10 kb/s, 20
kb/s, 50 kb/s, 100 kb/s, 125 kb/s, 250 kb/s, 500 kb/s, 800 kb/s, 1 Mb/s or Custom.
The method of copying settings is the same as I2C signal settings. See " I2C Signal
Settings" for details.

16.5.2 CAN Trigger

Touch Trigger Setting in the CAN trigger dialog
box to set the trigger condition:
• Start
beginning of the frame.
• Remote
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.
• ID + Data
ID and data.ID, ID Bits (11-bit or 29-bit), Curr ID Byte (1st, 2nd, 3rd, or 4th byte),
Data1 and Data2 can be set.
• Error

16.5.3 CAN Serial Decode

The configuration of CAN decoding is similar to that of I2C decoding.
