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.

Cette vidéo présente à quel point il est facile d'analyser le radôme et les pare-chocs en utilisant le R&S®QAR. vidéo, QAR, test de radôme Le principe du QAR expliqué en une minute

En savoir plus à propos des capacités de mesure et des fonctions uniques du QAR50 dans cette vidéo de 5 minutes. Le R&S®QAR50 est l'outil idéal pour tester précisément la qualité des radômes automobiles et des pare-chocs en fin de ligne (EOL).

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.

QAR50 Videoseries, Measurement results in detail Here we explain the measurement curves and images for different bands and clusters created by the QAR50 and how to interpret them.

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 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.

QAR50 Videoseries, Calibration, normalization and verification Here we focus on the terms calibration, normalization and verification in relation to the QAR50, what are the key considerations for each term and how to perform these important tasks.

Then we compare the uncertainty with the QAR50-Z44 verification set. 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.

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.

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.

User manual for the R&S®RadEsT radar essential tester describes how to install and operate the R&S®QAR50.

Découvrez pourquoi le R&S®QAR50 est l'outil parfait pour la mesure des radômes automobiles et des pare-chocs tout au long du cycle de développement. Du début de la R&D et de la caractérisation des matériaux, en passant par les processus de moulages complexes de conception des emblèmes, jusqu'aux tests de production en fin de ligne.

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.

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, 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.
