25 CAN Triggering and Serial Decode
3 Press the Trigger Type softkey; then, turn the Entry knob to select the serial slot
(Serial 1) on which the CAN signal is being decoded.
4 Press the Trigger on: 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.
5 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.
NOTE
If the setup does not produce a stable trigger, the CAN signal may be slow enough that the
oscilloscope is auto-triggering. Press the [Trigger] key, then press the Mode softkey to set the
trigger mode from Auto to Normal.
