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-Radio ^TM. 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.
