    The SY-CATR series are a variety of compact range measurement systems released by Sunvey Technologies for application in the millimeter wave detection field. As the millimeter wave radar features wide frequency band and small size, the SYCR series of different sizes can set up excellent experimental environment for millimeter-wave radar testing and design. Mainly used for testing automotive radars and their components, millimeter wave military/police radar products, and civilian millimeter wave antennas (millimeter wave reflector antennas, 5G millimeter wave communication antennas)


    The SY-68 probe spherical near-field antenna measurement system supports measurements in the 400MHz-8.5GHz, 600MHz-12GHz,400MHz~18GHz frequency bands, and supports secondary development of standard interfaces. Compared to the standard SY-24 system, it supports a larger measurement range (with a diameter of up to 2.5m), higher sampling density, active and passive measurements, and can also measure small base station antennas. It is suitable for testing and research institutions such as terminal manufacturers, third-party laboratories, and base station research and development.

  • SCR-5000

    Sunyield SCR-5000 cylindrical measurement system, the first linear array multi-probe cylindrical measurement system in the industry, innovatively integrates spherical multi-probe technology into the cylinder surface to ensure test accuracy while significantly saving space and cost. The system adopts multi-probe calibration technology and electronic solid-state switch to quickly collect data to measure the 3D pattern of the antenna, and at the same time expand S-parameter information such as standing wave and isolation according to user requirements. According to the characteristics of cylindrical system, this system is particularly suitable for the measurement of base station antennas with narrow vertical beam.
    In general, the measurement of 3D pattern can be achieved with the cost of a chamber for PIM or standing wave, and the system is especially suitable for prototype diagnostic testing in R&D and batch sampling in production.
