102 4000 X-Series Oscilloscopes Advanced Training Guide
4 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 [Help] > About
Oscilloscope.
1 Connect the channel-1 probe to the Demo 1 terminal and ground.
2 Press [Default Setup] on the scope’s front panel.
3 Press [Help]; then tap the Training Signals softkey.
4 Select and enable the CAN signal from the Training Signals menu.
5 Set channel- 1 to 500.0 mV/div.
6 Set channel- 1’s offset/position to +1.4 V.
7 Push the trigger level knob to automatically set the trigger level to
approximately 50%.
8 Set the scope’s timebase to 100.0 µs/div.
