CAN-Bus-Tester (CBT2)
A Powerful Tool for CAN-Protocol Analysis and Testing of Bus Physics
Overview
Many faults found in CAN bus systems have physical causes. With the CAN-Bus-Tester, it is possible to detect and analyze these faults. In addition, the most important logical analysis functions are also integrated into the Tester (otherwise found only in protocol analyzers). The Tester can be used with all bus systems with 11- or 29-bit identifiers according to ISO 11898-2. Particular emphasis was placed on simple operation. A USB-interface makes hot-plug&play possible between PC and Bus-Tester. Automatic baud rate detection and the self-connecting BusScan enable easy monitoring of the physical signal-to-noise ratio of the bus, sorted according to CAN-identifiers received. Generally, devices which transmit messages with low signal-to-noise ratio are highly susceptible to failures. Depending on the test strategy, various methods of identifying faults can be used, including setting various trigger events (identifier, physical and/or logical faults and error-frames). All faults are defined up to the individual bit position and are displayed with a time stamp. A trigger signal available via the external trigger output can be used for triggering an oscilloscope. A certain (faulty) CAN-message can thus be shown selectively on the oscilloscope.
Temporary faults on the bus or a slowly deteriorating signal quality, which can lead to the failure of the communication system, can be registered with an intuitive logger function. Since the Tester collects its data while the plant is running, costly downtime of machines and plants is avoided, and, all data can be protocolled.
