Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs

Lab #19: Decoding, Triggering, and Searching on LIN Serial Bus Signals

In this lab you will learn how to set up the scope to decode and trigger on
a LIN serial bus signal. In addition, you will learn how to use the scope's
automatic LIN Search & Navigation capability, as well as Segmented
Memory acquisition. This lab does not provide a tutorial on the LIN
protocol and signaling, which is primarily used in automotive applications.
To complete this lab, your scope must be licensed with the CAN/LIN
trigger and decode option (Option AUTO). You can verify the installed
options on your oscilloscope at [Help] > About Oscilloscope.
