CANscope The Ideal Tool to Analyze the CAN Bus Application Areas Typical application areas for CANscope are: > Analysis of the bus physics for analyzing specific features of a constructed network > Direct measuring mode for online evaluation of the data collected > Standalone operation for later analysis on a PC > Integration into automated test environments via the COM automation interface. 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 pro-gram. 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 avail-able. Hardware Interfaces CANscope offers the following connection options: CAN pass through (high-speed or low-speed), RS232 interface, and trigger input/output. Direct Measuring Mode After triggering a measurement, CANscope records the bus level with a configurable sampling frequency of up to 32 MHz and a maximum resolution of 20 mV. The module then transmits the data independently to the connected computer, where it can be inter-preted 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. and evaluated immediately by the evaluation software. 4/14 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 Standalone Mode In addition to the direct measurement mode, CANscope can be operated in a standalone mode without a PC, e.g. during test runs in a vehicle or in an industrial facility. Evaluation occurs later on the PC. More Information: www.vector.com/contact
