Solutions for Automotive Design
Automotive electronics development spans a wide range of challenges — from ECU validation and CAN bus debugging to sensor characterization and thermal management. UNI-T instruments provide the bandwidth, protocol support, and rugged field-ready tools that automotive engineers need throughout the design cycle, from prototype bench to production validation to field service.
Oscilloscopes — ECU & Bus Debugging
Automotive ECU development requires oscilloscopes with protocol decoding and mixed-signal capability. The MSO3034HD (350MHz, 12-bit) captures clean analog waveforms alongside decoded CAN, CAN-FD, LIN, SPI, and I2C traffic — essential for debugging communication between ECUs, sensors, and actuators.
For higher-bandwidth requirements in power electronics and motor drive applications, the MSO5054HD (500MHz, 12-bit) handles fast switching transients in inverter and DC-DC converter designs. For cost-effective multi-bench deployment, the MSO2204X (200MHz, 4-channel, nine-in-one) provides oscilloscope, logic analyzer, spectrum analyzer, and waveform generator in one instrument.
Waveform Generators — Sensor & Actuator Simulation
Simulating sensor inputs and actuator drive signals during ECU bench testing requires versatile waveform generation. The UTG2082X (80MHz, 2-channel) produces arbitrary waveforms for simulating sensor outputs while providing modulation capability for testing signal conditioning circuits. The UTG4162A (160MHz) offers higher frequency and lower distortion for more demanding applications.
Power Supplies — ECU Bench Power
Automotive ECUs need stable, adjustable power that simulates real vehicle electrical conditions — including voltage drops, cranking transients, and load dump scenarios. The UDP3305S (4-channel, 328W) provides low-noise linear output with programmable sequencing. For higher-power loads like motor drivers and heating elements, the UDP6942B (360W switching supply) handles the current demands.
Field & Service Tools
Automotive technicians and field engineers need rugged handhelds rated for vehicle electrical systems. The UT195DS dual-display industrial DMM provides IP65 protection with CAT III 1000V safety. The UT219DS dual-display AC/DC clamp meter handles up to 600A for testing harnesses and power distribution without disconnection.
Thermal imaging catches problems invisible to the eye — overheating connectors, uneven brake heating, HVAC leaks. The UTi720A (256×192) is designed for professional industrial inspection, and the UTi120T pocket imager fits in a tool pouch for quick spot checks.
