ETS-Lindgren's AMS-8800 Series Antenna Measurement System is a theta arm based antenna measurement test system. This system is ideally suited for automated measurement of antenna performance of wireless devices, and devices with embedded wireless functions. The AMS-8800 includes a distributed axis positioning system consisting of an azimuth rotator for rotating the AUT about the phi axis, and a separate theta arm positioner for elevating the measurement antenna around the AUT.
The scanning assembly uses a dual polarized quad-ridged horn antenna mounted on the theta scanning arm. The arm moves in an arc over a low dielectric foam column that supports the AUT. The entire scanning mechanism is housed inside of an anechoic lined chamber that provides RF isolation and a near-freespace environment. ETS-Lindgren's EMQuest™ EMQ-100 Antenna Measurement Software provides test automation, post processing, and tabular/graphical data output.
Theta Arm
The theta rotational arm scanning system provides a quick, convenient and accurate test method for wireless devices. It is a good choice for larger, heavier AUTs, especially those which may be gravity dependent.
Measurement Antenna
The dual polarized quad-ridged antenna in the theta arm provides broadband measurement in both polarizations. The standard frequency range is 690 MHz to 10 GHz. Options are available to increase the frequency range.
Device Mounts
A table-top mount is included for testing portable computing devices, desktop computing devices, small appliances, and customer premise equipment.
Compliance Testing
The AMS-8800 can easily be configured for upgrade to conduct CTIA Over-The-Air (OTA) testing and other wireless testing with optional test expansion packages.
