23 CAN/LIN Triggering and Serial Decode
3 Press the Trigger: softkey; then, turn the Entry knob to select the trigger
condition:
• SOF - Start of Frame — The oscilloscope triggers at the start of a frame.
• Remote Frame ID (RTR) — The oscilloscope triggers on remote frames with the
specified ID. Press the Bits softkey to select the ID.
• Data Frame ID (~RTR) — The oscilloscope will trigger on data frames matching
the specified ID. Press the Bits softkey to select the ID.
• Remote or Data Frame ID — The oscilloscope will trigger on remote or data
frames matching the specified ID. Press the Bits softkey to select the ID.
• Data Frame ID and Data — The oscilloscope will trigger on data frames
matching the specified ID and data. Press the Bits softkey to select the ID
and set up the number of data bytes and values.
• Error Frame — The oscilloscope will trigger on CAN active error frames.
• All Errors — The oscilloscope will trigger when any form error or active error is
encountered.
• Acknowledge Error — The oscilloscope will trigger when the acknowledge bit is
recessive (high).
• Overload Frame — The oscilloscope will trigger on CAN overload frames.
4 If you select a condition that lets you trigger on ID or data values, use the Bits
softkey and the CAN Bits Menu to specify those values.
For details about using the CAN Bits Menu softkeys, press and hold the softkey
in question to display the built-in help.
You can use the Zoom mode for easier navigation of the decoded data.
If the setup does not produce a stable trigger, the CAN signal may be slow enough that the
oscilloscope is AutoTriggering. Press the [Mode/Coupling] key, then press the Mode softkey
to set the trigger mode from Auto to Normal.
