ETS-Lindgren's Model AMS-8050 Antenna Measurement System supports testing a wide range of portable wireless devices and mobile handsets in free-space or using a head and hands phantoms. The AMS-8050 is a compact, fully anechoic RF enclosure for over-the-air (OTA) testing. It is used for wireless device measurements including pre-certification testing, design verification, performance verification, and production sample testing.

As a self-contained freestanding system, the AMS-8050 is the ideal solution when space is limited. The system’s portable chassis makes it an excellent choice for multiple research and development groups since it can be easily moved from one test group to another. The system includes integrated drawers for storing test equipment, cables and related accessories, allowing all of the components to conveniently travel with the system.

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

Pre-Compliance Testing

If you're using an external test house for certification testing, our system can help you go fully prepared. OTA performance measurements made in the AMS-8050 have shown good correlation to measurements made in larger, fully compliant chambers.

Compact Anechoic RF Enclosure

The AMS-8050 is an ideal solution when space is a limitation. It can be used as a self-contained test lab for making fast OTA performance measurements of small wireless devices and mobile handsets.

Self-Contained, Moveable System

The AMS-8050 is incorporated into a moveable chassis: the entire system may be transported between different test stations. Integrated equipment bays allow components required for testing to remain with the system. The ability to transport the system and store all components within the cart makes it an ideal solution for use by multiple research and development groups.

Easy Installation

The AMS-8050 System is easily installed into new or existing construction. Additionally, the moveable cart assembly allows for the system to be easily relocated within a testing facility.

EMQuest Data Acquisition and Analysis Software

The AMS-8050 System includes our versatile EMQ-100 Antenna Pattern Measurement Software. The software makes fully-automated pattern and frequency response measurements for both active and passive antennas, for either vector or scalar qualities, in either transmit or receive mode. Post-processing capabilities include calculations for directivity, gain, radiation efficiency, total radiated power, and total isotropic sensitivity. EMQ-100 also calculates industry specific quantities such as Near-Horizon Partial Isotropic Sensitivity required by the CTIA Test Plan for Mobile Station Over-the-Air Performance. Advanced graphing capabilities allow data to be shown in a variety of 2-D and 3-D formats, exported to Microsoft Excel™, PDF files, or saved in RTF format.
