CANscope

The Ideal Tool to Analyze the CAN Bus

CANscope is the measuring device for recording and evaluating the voltage levels on the CAN bus. CANscope offers a robust recording module and an easy-to-use evaluation software program. The recording module is connected to the PC via an RS232 or USB interface.

Features and Advantages

CANscope enables the developer to analyze the effects of:

• Various cable types
• Various cable lengths
• Bus drivers
• Bus terminations
• Failures
• EMC influences
• Errors in the ECU software or in CAN controllers

For targeted debugging, there are many trigger conditions available. For example, upon occurrence of a particular CAN message or error frame, or if a level is exceeded or under-run, the trigger is activated and the trigger environment is completely recorded.

Functions

The following central functions facilitate users’ work with the CAN bus:

• Oscilloscope Window for displaying the bus level
• Eye diagram for evaluating the signal quality
• Difference view for comparing voltage curves
