Automotive Electronics Test Solutions

Modern vehicles contain dozens of electronic control units communicating over CAN, CAN FD, and other in-vehicle networks. From powertrain controllers and ADAS modules to body electronics and infotainment systems, reliable bus communication is critical to vehicle safety and performance. Automotive engineers face unique challenges during development and validation. CAN FD introduces higher data rates and larger payloads that stress bus timing margins. Ground offsets between ECUs cause common-mode voltage issues. Electromagnetic interference from motors, solenoids, and switching regulators can corrupt bus traffic intermittently. Debugging these issues in a vehicle environment, often with limited physical access to test points, requires instruments that are portable, fast to set up, and capable of deep protocol analysis. Acute instruments are well suited to automotive bus debug. The TravelBus and TravelLogic portable analyzers fit easily into a vehicle cabin or test bench. Built-in CAN FD and CAN 2.0B protocol decoders display message IDs, data fields, DLC, error frames, and bit timing in decoded form. The LA4000 series provides the channel count and timing resolution needed for multi-bus captures across complex vehicle networks. The BusFinder dedicated protocol analyzer offers deep capture memory for long-duration recordings during drive cycles or environmental testing. All instruments connect via USB 3.0 to a laptop, making them practical for both lab and field use.
