QAR50 Videoseries, QAR50 and QAR50-R The differences in design, capabilities and applications of the QAR50 and the QAR50-R are explained and integration examples are shown.

QAR50 Videoseries This first video introduces the basic principles of microwave imaging and the R&S®QAR50 in general. This includes measurement clusters, reflection & transmission, traceability and test speed.

QAR50 Videoseries, Radome parameters and their effect This video focusses on measurement parameters such as attenuation, reflection and inhomogeneities, their importance for radar sensor performance and how to measure them with the R&S®QAR50.

Together with its partner Löhnert Elektronik, Rohde & Schwarz has introduced a fully automated turnkey solution for bumper production radar transparency testing based on the successful R&S QAR50. The lightweight and compact setup of the R&S QAR50-R facilitates precise positioning of the measurement antennas, allowing faster, more accurate and convenient testing. This leads to higher throughput and yeilds as well as more flexiblity to adapt to different DUTs, for End-of-line (EOL) measurements of bumpers and other exterior parts.

It compares the QAR50 microwave imaging solution with a quasi-optical vector network analyzer and shows how the optimum thickness of a radome can be calculated. QAR50 Videoseries, Material characterization This video is about the very beginning of bumper and radome measurement: material characterization.

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, 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.
