12.5.1 CAN Configuration
The correct setup of the protocol parameters and the threshold is the condition for
decoding the signal.
To set up and decode a CAN signal
1. Press the PROTOCOL key in the Analysis area of the front panel.
2. Select the bus that you want to use: B1 or B2.
3. Select the "Bus Type" = CAN.
4. Select "Configuration".
5. Select the "Source", the channel to which the input signal is connected.
6. Set the threshold. Use one of the following methods:
● Tap "Find Threshold". The instrument evaluates the signal and sets the thresh-
old.
● Enter the threshold value in the numeric field.
7. Set the other signal parameters according to the signal characteristics. All settings
are described below.
8. In the "Bus" menu, enable "Decode".
