  • Patent number: 7929461
    Abstract: A method of measuring bus traffic on a controller area network (CAN) is described. Accordingly, in one embodiment, a digital oscilloscope acquires the CAN bus signal in the form of a waveform in real-time. The waveform is converted into a bit stream, and the bitstream is analyzed to carry out various measurements in a CAN measurement system. The method may be used for continuous monitoring of bus traffic and measuring of various parameters related thereto, such as bus occupancy by a particular node. The acquired data may be analyzed for measuring bus occupancy by various types of CAN message frames. The user is presented with a data display and a graphical display of the measurements. Also, the user is allowed to enter an identifier for a node to obtain measurements relating to that particular node.
