Manufacture
GTS—PinProbe M6
Mobile terminal devices such as 5G phones, tablets, and laptops (User Equipment, UE) face new challenges in OTA testing during the mass production stage: higher testing frequencies and more antennas to be tested. These challenges have led to a decrease in testing accuracy and a sharp increase in testing time for traditional equipment. To solve this problem, General Test has innovatively launched a high-performance and cost-effective testing system, PINPM6, which has the ability to perform parallel testing of up to 6 mobile phones. This is mainly due to the instrument’s multi-channel transmission and reception capabilities, the beamforming control of the probe antenna, the isolation design of the absorptive material, and the parallel execution mode of the software. PINPM6 uses a frequency range of 0.6-6GHz and can be used to test 2/3/4/5G, Bluetooth, Wi-Fi, and other technologies.
CATR
GTS-RP Systems
CATR is a high-performance and quickly deployable 5G NR FR2 OTA compact range testing system. General Test has broken through traditional design for reflectors and feed systems, and the key quality indicator for quiet zones is increased by 50% compared to traditional systems, with a measurement range of up to 70% of the reflector; the overall design of measurement and control software, testing instruments, links, and mechanical turntables work in synergy, resulting in a testing efficiency that is 60% higher than traditional darkrooms; the fusion design of absorbing materials, reflectors, feed systems, and microwave darkrooms makes the new generation of compact ranges have a compact internal structure and small outer dimensions, making them easy to transport and install.

The Keytest RN200 OTA testing system is mainly used for testing the wireless performance of 5G terminals and millimeter-wave radar. It is a small, large quiet zone, and multifunctional integrated (All-in-One) millimeter-wave testing system solution. The Keytest RN200 provides a complete “platform + testing system” solution, offering a universal software platform and cloud service platform for engineers to develop and validate the OTA performance of wireless terminals. The system also allows engineers to complete signal processing and algorithm testing according to their needs.
Spherical Near Field
GTS-CH1900
CH1900 is a multifunctional and fast measurement system designed for the research and production stages of 5G millimeter-wave devices. It is suitable for measuring various phased array antenna technology components (chips/terminals/base stations/automotive radars/satellite antennas, etc.), with functions such as amplitude and phase calibration, antenna parameter measurement, and RF parameter measurement. CH1900 is optimized in terms of mechanical, RF components, calibration methods, and test methods around the system’s goals, enabling high-precision measurements of larger test components in small spaces. Its compact split design enables convenient and rapid transportation and installation, making it suitable for research offices and laboratories.
The design of CH1900 has undergone rigorous system-level hardware simulation. It uses custom millimeter-wave measurement antennas that have wideband, low scattering, and low cross-polarization characteristics. The system is also equipped with new EPP absorption materials that are sturdy, durable, environmentally friendly, moisture-proof, and dust-free. The high-precision, fully-transparent turntable design can effectively reduce obstruction and improve testing efficiency.
Reverberation Chambers
The reverberation chamber consists of reflecting metal walls, a turntable, horizontal and vertical stirrers. Various reflections form a multipath reflection environment in the chamber. By moving or rotating the turntable and stirrers, the electromagnetic field from various directions is superimposed, mathematically representing the superposition of plane waves in different directions, achieving a mathematical sense of the quiet zone.
