Description

ETS-Lindgren's Model AMS-8050 is a compact, fully anechoic RF enclosure for making over-the-air (OTA) performance measurements. The AMS-8050 is freestanding and built on a moveable cart configuration; it fits into parent buildings without special installation or construction. This over-the-air test system for wireless device measurement may be used for rapid prototyping, design validation, precertification testing, performance measurement, and production sampling.

Features

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 ExcelTM, PDF files or saved in RTF format.

Applications

The AMS-8050 System allows for efficient Over-the-Air performance measurement of:

• Fully automated 2-D (polar) and 3-D (spherical) antenna pattern measurements
• Total radiated power (TRP)
• Effective isotropic radiated power (EIRP)
• Total isotropic sensitivity (TIS),
• Effective isotropic sensitivity (EIS)
• Near-horizontal partial radiated power (NHPRP)
• Near-horizon partial isotropic sensitivity (NHPIS)

Special Note: The dimensions illustrated are the minimum clearances required, with a small allowance on each side to pass the system through doorways and corridors. If these dimensions are not met, the AMS-8050 may be split into two sections (System Cart, Drive Cart). Contact ETS-Lindgren Sales at the time of order if you determine there is a need to split the system.
