AMS-8923 Over-The-Air Test Lab

ETS-Lindgren’s Model AMS-8923 Antenna Measurement System is a high speed, multi-antenna array test system. This model is ideally suited for automated measurement of antenna performance of wireless devices, and devices with embedded wireless functions.

The AMS-8923 Antenna Measurement System includes a custom Multi-Antenna Array Ring. This ring houses a system of dual-polarized antennas. Together, these antennas support testing between 700 MHz and 6 GHz.

An integrated laser alignment system assists with DUT positioning. 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.

The baseline AMS-8923 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 of the following:

  • Cellular (CTIA) Upgrade Package: Cellular testing capability per CTIA Test Plan for Mobile Station Over-The-Air Performance (CTIA OTA Test Plan)
  • Wi-Fi Upgrade Package: Wi-Fi Testing per Wi-Fi Alliance Test Plan for RF Performance Evaluation of Wi-Fi Mobile Converged Devices
  • WiMAX Upgrade Package: WiMAX Testing per WiMAX Forum Radiated Performance Tests (RPT) for Subscriber and Mobile Stations
