15.5 CAN Decoding
The oscilloscope samples the CAN or CAN-FD (optional) 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 or CAN-FD (optional) 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. CAN-FD Baud and FD Sample
Position items are available only when the CAN-FD option is installed. CAN-FD Baud
is specified as the baud rate of the CAN-FD serial bus.
