The AMS-8800 includes a distributed axis positioning system consisting of an azimuth rotator for rotating the DUT about the phi axis, and a separate theta arm position for elevating the measurement antenna around the DUT.

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 DUT. 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.

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 DUTs, especially those which may be gravity dependent.

The dual polarized quad-ridged antenna in the theta arm provides broadband measurement in both polarizations. The standard frequency range is 700 MHz - 10 GHz. Options are available to increase the frequency range.

A table-top mount is included for testing portable computing devices, desktop computing devices, small appliances, and customer premise equipment.

The AMS-8800 can easily be configured upgraded to conduct over-the-air testing of wireless devices per CTIA, Wi-Fi, and WiMAX RPT specifications. Please contact ETS-Lindgren for further information.
