A CANalyzer developer designs, develops, and tests software for the CANalyzer tool, a high-performance measurement software for analyzing network systems in vehicles. They work on protocols like CAN, LIN, MOST, FlexRay, or Ethernet. Their role involves configuring the CANalyzer environment, identifying network issues, analyzing data traffic, and validating network communication. They also create simulation models, automate testing, and generate reports. They need a strong understanding of vehicle bus systems and excellent programming skills, typically in CAPL (CAN Access Programming Language). They collaborate closely with other engineers to ensure the tool's efficiency and accuracy in network analysis.
