CAN Triggering

To set up the oscilloscope to capture a CAN signal, see
Signals"
The Controller Area Network (CAN) trigger allows triggering on CAN
version 2.0A and 2.0B signals.
A CAN message frame in CAN_L signal type is shown below:
After setting up the oscilloscope to capture a CAN signal:
1 Press [Trigger].
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob

• Differential (H-L) — The CAN differential bus signals connected to an
analog source channel using a differential probe. Connect the probe's
positive lead to the dominant- high CAN signal (CAN_H) and connect
the negative lead to the dominant- low CAN signal (CAN_L).
Dominant low signals:
Rx — The Receive signal from the CAN bus transceiver.
•
Tx — The Transmit signal from the CAN bus transceiver.
•
CAN_L — The actual CAN_L differential bus signal.
•
Differential (L-H) — The CAN differential bus signals connected to an
•
analog source channel using a differential probe. Connect the probe's
positive lead to the dominant- low CAN signal (CAN_L) and connect
the negative lead to the dominant- high CAN signal (CAN_H).
