CAN Decoding (Option)

For the data frame format of the CAN bus, please refer to "CAN Trigger". The
oscilloscope samples the CAN signal at the specified sample position. For CAN
decoding, you need to specify the CAN signal type and the sample position.
Press MATH  BUS1  Decode and select "CAN" to open the CAN decoding
function menu.
If the current trigger type of the trigger system is CAN, press CopyTrig to copy the
current CAN trigger configurations (including the source channel, signal type, signal
rate, and sample point) to the CAN decoding configurations. After that, you can still
set the CAN decoding parameters according to the introductions below.
Note: The copy function is only available when the current trigger type is "CAN";
otherwise, CopyTrig is not available.
1. Source
Press Source and select any channel (CH1-CH4) as the source channel.
2. Signal Type
Press Signal Type to select the desired signal type.
Rx: the receiving signal from the CAN signal line.

Tx: the transmitting signal from the CAN signal line.

CAN_H: the actual CAN_H bus signal.

CAN_L: the actual CAN_L bus signal.

Differential: the CAN differential bus signals connected to an analog

channel using a differential probe. Connect the probe's positive lead to
CAN_H and connect the negative lead to CAN_L.
3. Baud
Press Baud to select a baud rate (100 kb/s, 125 kb/s, 250 kb/s, 400 kb/s, 500
kb/s, 800 kb/s, 1 Mb/s or User) that matches your CAN bus signal. When "User"
is selected, press Setup; use
to adjust the signal rate with a small step value or rotate the outer knob of the
navigation knob

or the inner knob of the navigation knob
to quickly adjust the signal rate within a relatively larger
