Comprehensive automotive testing is crucial for chipset developers, ECU suppliers, vehicle manufacturers
and certification bodies to ensure faultless performance, particularly in safety-critical applications. As a
leading worldwide provider of test and measurement software, instruments and systems, Rohde & Schwarz
employs its technical expertise to develop leading-edge solutions for the entire automotive lifecycle from
predevelopment to production.

C-V2X testing from the lab to proving ground
Rohde & Schwarz will show a C-V2X test solution that allows traffic scenarios involving multiple simulated
vehicles and the communications between them to be tested in the laboratory and on the proving ground in a
precise and repeatable way. This enables the correct operation of C-V2X applications such as Emergency
Brake Warning (EBW) in realistic and demanding traffic scenarios to be verified using a minimum of test
equipment and the same test setup from lab to proving ground. The system comprises an R&S CMW500
wideband radio communication tester, an R&S SMBV100B vector signal generator (lab only) and a R&S
BBA150 amplifier. In addition, the R&S TSMx6 network scanner allows C-V2X PC5 network coverage
measurements in the field and verifies the correct operation of Road Side Units (RSUs) and communications
between cars (V2V).

Automotive radar object simulation
Another highlight is the new radar test system, which allows complex traffic scenarios to be electronically
generated entirely over the air interface for testing radar based advanced driver assistance systems (ADAS)
in benchtop development, HIL, VIL and production. The solution consists of the R&S AREG800A automotive
radar echo generator as a backend and the R&S QAT100 antenna array as a frontend. Laterally moving
objects can be simulated by electronically switching individual antennas on and off in the frontend. This
allows tests currently performed in real-world test drives to be relocated to the lab, enabling errors to be
detected at an early stage and delivering significant cost savings.

Radome and bumper material analysis
The R&S QAR50 from Rohde & Schwarz is ideal for testing radomes and bumper material quality in
development and production. The R&S QAR50 uses microwave imaging, which has numerous advantages
compared to conventional, unfocused single-point measurements. Particularly in production, simple and
reliable operation and short cycle times are crucial. The user-friendly interface of the R&S QAR50 simplifies
measurements in the automotive radar frequency band – even for users without detailed RF knowledge.

5G TCU development
The R&S CMX500 one-box radiocommunications tester provides high-performance 5G automotive
measurements with comprehensive test coverage including RF, protocol and application testing. It covers the
entire integration cycle from chipsets to TCUs and complete vehicles. The R&S CMX500 provides extensive
testing capability, supporting all 5G NR deployments covering LTE, 5G NR FR1 and FR2 in non-standalone
(NSA) and standalone (SA) mode, for both FDD and TDD with an effortless setup and outstanding
performance. The 5G tester reaches its market-leading high performance with its ability to handle data rates
of 10 Gbps and beyond.

Automotive Ethernet compliance
Developments in Advanced Driver Assistance Systems (ADAS) and infotainment are driving up automotive
data rates. As they grow, it becomes increasingly important to ensure the quality and performance of the
cables and components of the communication channel. Automotive Ethernet is a key enabler for high data
rate applications, as well as for data backbone, connecting different domain controllers. The R&S RTP
oscilloscope from Rohde & Schwarz enables compliance testing on the next evolution of the automotive
Ethernet standard all the way up to MultiGBASE-T1.

UWB module development
The fine-ranging and security capabilities of Ultra-Wideband (UWB) technology make it very well suited for
automotive applications such as vehicle access control, ADAS, gesture recognition and parking assistance.
Testing the performance of UWB devices is important in the lab and on the production line to ensure
compatibility and correct operation. The R&S CMP200 radio communication tester is ideal for solving UWB
test challenges in volume production as well as in R&D. The tester combines the capabilities of a signal
analyzer and a signal generator in a single instrument. In combination with Rohde & Schwarz shielded
chambers and the company’s WMT software service to implement automated wireless manufacturing
testing, the R&S CMP200 offers a complete solution for transmitter, receiver, time of flight (ToF) and angle of
arrival (AoA) measurements in conducted and radiated mode, compliant with IEEE 802.15.4a/z
specifications.
