At Automotive Testing Expo Europe 2023 in Stuttgart, Rohde & Schwarz will demonstrate a wide range of cutting-edge test solutions that support automotive applications. With test solutions on show that cover automotive radar, Ethernet, 5G and UWB, the company enables the automotive industry to make the next level of autonomous driving reality.

Discover why the R&S®QAR50 is the perfect tool for measuring automotive radomes and bumpers throughout the development lifecycle. From early R&D and material characterization through the complex molding processes of design emblems until end-of-line production testing.

QAR50 Videoseries, QAR50-K20 Phase mask measurement Precise insertion phase measurements with reference to a mask to detect anomalies such as injection moulding points, inconsistent paint thickness or material inhomogeneities..

QAR50 Videoseries, Resolution and sensitivity In this video we take a close look at how the images, the effect of incorrect positioning, the cluster design, the high resolution option and the concept of weighted apertures.

At Automotive Testing Expo Europe 2022 in Stuttgart, Rohde & Schwarz will demonstrate a wide range of advanced test solutions that support automotive applications. In the focus of the company at the show will be C-V2X, GNSS and automotive radar solutions which pave the way for the realization of advanced driver assistance systems (ADAS). Another important topics are connectivity test solutions for Automotive Ethernet, 5G and UWB.

QAR50 Videoseries, Resolution and separability Here we examine the instrument’s resolution and capability to distinguish between different potential sources of irregularities inside the radome. A closer look at phase resolution and practical demonstration using cut outs is included.

QAR50 Videoseries, Effects of curvature Radomes and bumpers are usually not flat so this video looks at how curvature influences the measurement result, further showing the advantages of microwave imaging over network analyzer techniques for material quality analysis..

QAR50 Videoseries, Accreditation and traceability of results This video uses the quasi-optical certified calibration setup to illustrate how the accreditation values are generated, explains its benefits and limitations. Then we compare the uncertainty with the QAR50-Z44 verification set.

QAR50 Videoseries, Positioning accuracy Here we explain in more detail how the images are created and the effect of an incorrect positioning of the sample. We also take a close look at the cluster design, the high resolution option and the concept of weighted apertures.

QAR50 Videoseries, QAR50-K10 Frequency response Use this option to understand the variation of transmission and reflection characteristics against frequency and check the resonant frequency is in the middle of the automotive radar band. This information can be used to adapt the thickness of the material and to calculate permittivity. It has particular advantages for sample analysis in production.

Rohde & Schwarz is presenting its solutions live at productronica 2021, the leading global trade show for electronics development and production. The focus is on T&M equipment for latest technologies including automotive radar, satellite communications, Wi-Fi 7 and 5G. High throughput and low cost are essential in production environments, and Rohde & Schwarz solutions support exactly these goals. Trade show visitors will find the following Rohde & Schwarz highlights and more in hall A1, booth 375 at Messe München.

Application video: QAR50-R robotic solution For larger samples such as grills or bumpers, it might be more applicable to move the sample instead of the measurement device. Therefore, the QAR50-R was developed. Follow me on a visit to our Partner Löhnert Elektronik where the QAR50-R is produced.
