Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs
Lab #18: Decoding, Triggering, and Searching on CAN Serial Bus
Signals
In this lab you will learn how to set up the scope to decode and trigger on a CAN
serial bus signal. In addition, you will learn how to use the scope’s automatic CAN
Search & Navigation capability, as well as Segmented Memory acquisition. This
lab does not provide a tutorial on the CAN protocol and signaling. 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
