CAN Decoding

The oscilloscope samples the CAN signal at the specified sample position, and judges
each data point to be logic "1" or logic "0" according to the preset threshold level.
You need to specify the CAN signal type and sample position.
In the Decode menu, click or tap the drop-down button of Bus Type to select CAN,
then configure the parameters for CAN decoding.
