Verifying LIN Serial Bus Communication 10
Agilent InfiniiVision 7000B Series Oscilloscopes Evaluation Guide 55
The oscilloscope should now be decoding the LIN data, but not yet
triggering on this LIN signal. Let’s now set up the oscilloscope to trigger
specifically on LIN frame ID 12 hex.
12 Press [Trigger]; then, select the LIN triggering mode.
13 Press Trigger: Sync; then, select the ID-Frame ID trigger mode.
14 Press Frame ID 0xXX; then, select 0x12.
The oscilloscope should now be triggering on frame: 12 hex. Notice the
last byte in the serial decode string. This is the checksum byte. This byte
is sometimes displayed in red. This is an indication of checksum errors.
Let now trigger on frame ID: 21 hex so that we can see another type of
error condition.
15 Press Frame ID 0x12; then, select 0x21.
