TCU manufacturing testing

Efficient production test solutions for multi-technology Telematics Control Units

The Telematics Control Unit (TCU) is the fundamental part of a vehicle that enables wireless connectivity to the outside world. It integrates modems such as a Network Access Device (NAD) for various wireless standards such as 2G, 4G (LTE), 5G, C-V2X, Bluetooth (BLE), UWB, WiFi & GNSS as well as infotainment services such as AM/FM, DAB+ and HD-RadioTM. Additionally, the TCU also hosts the supporting modules such as antennas, eSIM, signal processing, power management and interfaces to in-vehicle networks such as CAN and Ethernet. Because it enables the wireless connectivity for important functions such as eCall, ADAS, OTA software updates, diagnostics, audio and navigation, testing its correct operation on a functional and RF level is essential in the lab and on the production line.

TCU manufacturing test systems from Rohde & Schwarz provide complete test coverage across all required technologies and provide the speed and scalability necessary to ensure efficient measurement of these highly complex and critical modules.

Your challenges

  • Ensure full, standards-compliant test coverage for multi-technology TCUs
  • Maximize efficiency of operational production lines by increasing throughput & maximizing yield
  • Quickly set up new production lines or adapt existing ones to bring new products to market
  • Minimize lifecycle costs and equipment footprint
  • Production sites work on global scale and require local full service & maintenance support
