Antenna measurement test chamber AMS-7000

EMChigh-capacity

ETS-Lindgren's AMS-7000 Wireless OTA Reverb Test System is designed to perform accurate and repeatable SISO TRP, TIS, Throughput, and MIMO Throughput measurements. The system is based on the companys long-standing line of SMART reverberation chambers and proven EMQuest antenna 5G FR1 Over-The-Air (OTA) test solutions are now available! ETS-Lindgren offers a turnkey package which will enable support for 5GNR SISO non-standalone [NSA] and/or standalone [SA] testing in the FR1 band. Key Features SISO TRP, TIS, and Throughput Measurements MIMO Throughput Measurements Antenna Efficiency Measurements Direct Correlation to CATL Lab Results Faster Test Times Operates with EMQuest Software Freestanding Moveable Cart Configuration Chamber The AMS-7000 uses two Z fold tuners, a DUT turntable, and a measurement antenna turret to improve isotropicity and homogeneity. These features allow the system to make measurements at different speeds and levels of accuracy. SISO TRP, TIS, and Throughput TRP measurements made in a reverb chamber rely on a continuous sampling of the average power density in an over-moded environment while the DUT is transmitting at its full power. The accuracy, with which the average power can be measured, directly correlates with the number of independent samples that are available to be taken. The TIS measurement is the converse of TRP; the power density in the chamber is controlled for the downlink path by the communication tester. The DUT responds to samples of this environment as it moves to a series of different locations in the varying modal environment. The TIS value is then derived from the reported data validity threshold after chamber corrections .
