Using the CANbus Option
Using the CANbus Option Overview
CANbus TD (Trigger and Decode)
The CANbus TD option contains powerful software algorithms to extract serial data information from physical
layer waveforms measured on your oscilloscope. The extracted information is overlaid (annotated) on the actual
physical layer waveforms, and color-coded to provide fast, intuitive understanding. This option includes GM
CAN/LAN, CAN H-L, and GM CAN H-L. You may notice these items available on some controls.

The CANbus TD option allows triggering on CAN Frames and Errors. Frame triggering can be set to trigger on any
frame, one specific Frame ID, a range of Frame IDs, Remote Frames and Errors. Frame triggering and data
triggering can be done for a single ID or message or a range of IDs and data by using the conditional trigger
capabilities. Other powerful and user-friendly features included in CANbus TD include:

The ability to trigger and decode CAN at bit rates from 10 kb/s to 1 Mb/s.
The ability to create powerful, conditional Frame ID and Data triggers.
Triggering on CAN protocol errors and remote frames.
If you are unfamiliar or are just learning about CAN, start by using the simplest trigger conditions (All Frames or
Frame ID). Next, experiment with an ID and Data to trigger on a specific value. Then, try a conditional ID + Data
trigger (ID Greater Than or In Range).
