Key Product Information


The AMS-8041 is equipped with a Model 3165-02 dual polarized Vivaldi antenna capable to measure both linear and circular measurements over the frequency range of 400 MHz to 6 GHz. The antenna is mounted on a removable access panel at the top of the enclosure. The antenna can be interchanged with another antenna of a different frequency if needed. Two antennas are used for communication with the DUT.

Two-Axis Positioner

3D antenna measurements can be made for both active and passive antennas using the AMS-8041's two-axis positioner. The positioner is constructed of low- dielectric materials and is designed for hand-held devices weighing up to 1 kg (2.2 lb.). The positioner is controlled by EMQuest™ Software.

Anechoic Absorber

FlexSorb™, a flexible RF absorber that bends and returns to its original form, is used in AMS-8041 to eliminate breakage from extended lab use. The absorber is performance optimized and limits reflections and moding, for more accurate, repeatable measurements. Tapered wedges line the walls, pyramidal absorber is used on the floor, and lossy foam lines the antenna. 

EMQuest Data Acquisition and Analysis Software

The AMS-8041 System includes our versatile EMQ-100 Antenna Pattern Measurement Software. The software makes fully-automated pattern and frequency response measurements for active and passive antennas. 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 2D and 3D formats, exported to Microsoft Excel™, PDF files or saved in RTF format.
