The AMS-8500 from ETS-Lindgren is an Antenna Measurement System for Over-The-Air (OTA) performance measurements. It can perform antenna testing from 690 MHz to 6 GHz with extension to frequencies up to 10 GHz via additional antennas. This system is designed to automatically measure the antenna performance of wireless devices and devices with embedded wireless functions as well as traditional antenna pattern measurements for passive antennas. It supports far-field measurements at a separation distance of approximately 4.9 m (16 ft). The AMS-8500 is fully configured to perform both R&D and type approval measurements for transmitting power and receiver performance of wireless devices in accordance with the CTIA Over-The-Air (OTA) test plan.
This antenna measurement system features a rectangular chamber with Multi-Axis Positioning System (MAPS) for high-resolution 3D pattern testing. The MAPS rotates the device under test (DUT) around two orthogonal axes for full spherical coverage and to minimize measurement errors. The chamber is compatible with a variety of RF instrumentation for user-specific measurement requirements. This system can be configured to perform generic antenna measurements by using a multi-channel Vector Network Analyzer (VNA).
The AMS-8500 comes with EMQuest Data Acquisition and Analysis Software that supports data acquisition in either the great circle-cut or conical-cut test sequence to perform full spherical antenna measurements for Instruments Under Test (IUTs) in either transmit or receive mode. Post-processing calculations include derivation of antenna half-power beam-width, directivity, gain, radiation efficiency, total radiated power, and total optional isotropic sensitivity.
The AMS-8500 antenna measurement system has a shield dimension of 7.3 x 3.7 x 3.7 m and an overall dimension of 7.5 x 3.9 x 3.9 mm.
