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.

Abstract: A system and a method for simultaneous measurement and analysis of network signals on multiple communication networks are described. Accordingly, in one embodiment, the system accepts signals from two communication networks. The two networks may be following different protocols. A time-correlated measurement of corresponding frames of two protocols may be provided. Information pertaining to message frames of different networks may be displayed simultaneously.
