​ETS-Lindgren's AMS 8900 Series Antenna Measurement System is a high speed, multi-antenna array test system designed for fully compliant radiated wireless antenna measurements. The AMS-8900 system includes a custom multi-antenna array ring. This ring houses a system of dual-polarized antennas. With a switch control box integrated on the ring, the test system provides fast switching between antennas for high speed testing. Its centralized system configuration supports easy maintenance and superior reliability.

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 Product Information

Multi Antenna Array

23 or 47 dual-polarized SISO antennas spaced every 15º or 7.5º with anechoic absorber material between them to provide high speed, accurate and repeatable test performance.

Integrated Laser Alignment

An integrated laser alignment system assists in quick and precise DUT positioning. 

System Frequency

Supports testing between 690 MHz and 6 GHz as standard, or optionally 400 MHz to 6 GHz or 690 MHz to 10 GHz.

Turnkey Systems Availability

The baseline AMS-8900 Series Antenna Measurement System is designed as a general platform to support testing of various wireless devices and mobile handsets. This chamber can be equipped with optional upgrade packages to support compliant measurements.
