Features

Comprehensive Distributed Antenna System (DAS)

The RayZone® 9000 system uses a multi-probe antenna system architecture that allows for independent installation of probe antennas for SISO and MIMO measurements through a modular design, increasing system configuration flexibility. The modular installation not only reduces the complexity of system construction, but also improves the accuracy and consistency of system installation.

Radiation two-stage (RTS) MIMO testing

The RayZone® 9000 system supports MIMO testing capabilities based on the RTS method. For example, the RTS method is used for 4X4 MIMO testing.

EPP rigid foam absorbing material

Absorbing material is one of the most important core components of microwave anechoic chamber, and its performance and product quality have a direct impact on the overall indicators of the project. The full range of products of General Testing adopts the high-performance, environmentally friendly fourth-generation absorbing material produced based on the world’s leading technology – Polypropylene Foam (EPP) absorbing material with patented technology of General Testing, which has incomparable advantages of traditional polyurethane sponge (PU) materials.

Multi-probe method (MPAC) MIMO testing

The RayZone® 9000 system MIMO test supports both tester-based and tester-based test schemes that include only downlink one-way channel simulation to evaluate the performance of the downlink throughput of the terminal. During the test, only the 8-probe antenna or 16-probe antenna of the horizontal middle ring can be used for the evaluation test under the 2D channel model, and the probe antenna on the upper and lower horizontal double rings can also be selected for the evaluation test under the 3D channel model. There are two test scenarios for the actual base station.

Broadband Low-Scattering Dual-Polarization Measurement Probe Antenna

The measurement antenna of the RayZone® 9000 is a wideband low-scatter dual-polarized antenna (MA-2800) designed by General Purpose Testing. It can be used for gain calibration, measuring probes and generating broadband interference signals.

Multi-dimensional MIMO performance evaluation

The RayZone® 9000 MIMO test supports SIR-based throughput testing and RS-EPRE-based throughput testing. The SIR-based throughput test function mainly refers to the MIMO test standard of CTIA, which is to continuously increase the additional AWGN noise power and change the SIR of the environment where the DUT is located under the condition of the downlink power output of the fixed channel simulator, so as to evaluate the throughput performance of the DUT under different SIR conditions.
