Keysight InfiniiVision HD3-Series Oscilloscopes User's Guide 323
• Display — When CAN symbolic information is loaded, you can select between
Hex and Symbolic display of the decoded data.
Notes • The CAN triggering and serial decode option is license-enabled.
• If the decode line does not appear on the display, press the [Protocol Decode] key
to turn it on.
• If the oscilloscope is stopped, press the [Run/Stop] key to acquire and decode
data.
• If the setup does not produce a stable trigger, the CAN signal may be slow
enough that the oscilloscope is Auto triggering. Press the [Mode] key to set the
trigger mode from Auto to Trig'd.
• You can use the horizontal [Zoom] window for easier navigation of the decoded
data.

Loading and Displaying CAN Symbolic Data
When you load (recall) a CAN DBC communication database (*.dbc) file into the
oscilloscope, its symbolic information can be:
• Displayed in the decode waveform and Lister window.
• Used when setting up CAN triggering.
• Used when searching for CAN data in the decode.
To recall a DBC file into the oscilloscope:
1 From the main menu, choose File > Open....
2 In the Open dialog box, from the Format drop-down menu, select CAN Symbolic
