Improving Antenna Directivity Measurement with the SUNYIELD SCR-5000 Cylindrical Antenna Measurement System

SUNYIELD Technologies presents the innovative SCR-5000 cylindrical near-field antenna measurement system, designed to revolutionize directivity measurement of antennas. With its broad frequency range, extensive quiet zone measurement capabilities, and advanced features, the SCR-5000 delivers accurate results while providing space and cost savings. In this article, we will explore the introduction, applications, and advantages of SUNYIELD’s SCR-5000, highlighting its role in enhancing directivity measurement of antenna.

Introduction to the SCR-5000 Cylindrical Antenna Measurement System

Frequency Range and Quiet Zone: The SUNYIELD SCR-5000 supports a frequency range of 690MHz to 8.5GHz, enabling comprehensive measurement capabilities across various communication standards. With its generous 3-meter diameter quiet zone measurement range, the system provides ample space for precise antenna testing.

Linear Array Multi-Probe Technology: As the industry’s first linear array multi-probe cylindrical measurement system, the SUNYIELD SCR-5000 integrates spherical multi-probe technology into the cylinder surface. This innovative design ensures accurate test results while optimizing space utilization and reducing costs.

Applications of the SCR-5000 Cylindrical Antenna Measurement System

3D Antenna Pattern Measurement: The SCR-5000 utilizes multi-probe calibration technology and an electronic solid-state switch to facilitate 3D antenna pattern measurement. This capability enables businesses to evaluate the performance and directivity of their antennas accurately.

Base Station Antennas: Given the characteristics of the cylindrical system, the SCR-5000 is particularly suitable for measuring base station antennas with narrow vertical beams. Its unique design and multi-probe configuration ensure efficient and precise testing, making it an ideal solution for evaluating the performance of these antennas.

Advantages of the SCR-5000 Cylindrical Antenna Measurement System

Fast Test Speed: The SCR-5000’s multi-probe design allows for convenient horizontal mounting of the Device Under Test (DUT), enabling test efficiency comparable to spherical multi-probe systems. This fast test speed facilitates rapid evaluation of antenna directivity, reducing overall testing time.

Cost-Effective System: Compared to spherical near-field systems, the cylindrical near-field test system, such as the SCR-5000, offers significant space-saving and cost-saving advantages without compromising test accuracy. This makes it an appealing choice for businesses seeking accurate and cost-effective antenna performance evaluation.

Over-Sampling Technology: The SCR-5000 features a slidable multi-probe structure that enables Z-axis over-sampling for larger antenna measurements. This over-sampling technology ensures accurate and detailed characterization of antennas, resulting in precise directivity measurement outcomes.


SUNYIELD’s SCR-5000 Cylindrical Antenna Measurement System empowers businesses to enhance directivity measurement of antennas. With its wide frequency range, expansive quiet zone, multi-probe calibration technology, and cost-effective design, the SCR-5000 provides a powerful solution for accurate evaluation of antenna performance. Whether for base station antennas, R&D prototype testing, or production batch sampling, SUNYIELD’s commitment to innovation ensures that the SCR-5000 delivers reliable and efficient measurement capabilities.
