Key Product Information


The AMS-8040 is equipped with a dual-polarized Vivaldi antenna (model 3165-02) for 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 dual-polarized antennas are used for communication with the DUT. Two-Axis Positioner 3D antenna measurements can be made using the AMS-8040's two-axis positioner. The positioner is constructed of low-dielectric materials and is designed for handheld devices weighing up to 454 g (1 lb). The positioner is controlled by EMQuest™ Software. 

RF Shielding

The RF-shielded anechoic enclosure is compact and freestanding; ideal when space is limited.  The portable chassis makes it an excellent choice for multiple research and development groups since it can be moved from one test group to another through doors as small as 0.9 m x 2.1 m (3 ft x 7 ft). The RF shielded door uses compressible finger stock in a "knife edge" configuration. Two latch points with a single point handle provide secure sealing and one-hand operation. Typical RF isolation of both the shielding and door is greater than 80 dBs. 

Anechoic Absorber

FlexSorb™, a flexible RF absorber that bends and returns to its original form, is used in AMS-8040 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.  

Connector Panel

A connector panel (bulkhead feedthrough) is included with the AMS-8040. The panel includes a power line filter, two SMA connectors and three type N Connectors for customer use. Two ST connectors are reserved for the two-axis positioner, and two additional type N connectors are reserved for the two DUT communication antennas. 

EMQuest Data Acquisition and Analysis Software

The AMS-8040 System includes our versatile EMQ-100 Antenna Pattern Measurement Software. The software makes fully-automated pattern and frequency response measurements for active 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 (NHPIS) 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.
