Description

The AMS-8050 Antenna Measurement System is freestanding and built on a moveable cart configuration; it fits into parent buildings without special installation or construction. This over-the-air test system for wireless device measurement may be used for:

* Rapid prototyping of wireless devices
* Design validation
* Pre-certification testing
* Performance measurement
* Production sampling

The AMS-8050 Antenna Measurement System is an ideal solution when space is a limitation as it is a self-contained, test lab for making fast, over-the- air performance measurements of small wireless devices and mobile handsets, as well as short range APM. Integrated drawers allow components required for testing to remain with the system. It is incorporated into a movable chassis so the entire system may be transported between different test stations. The ability to transport the system and store all components within the cart makes it an ideal solution for multiple research and development groups.

Small in size but big on operational throughput, the AMS 8050 Antenna Measurement System lets you make fully automated 2-D (polar) and 3-D (spherical) antenna pattern measurements. You can measure quantities such as : total radiated power (TRP), effective isotropic radiated power (EIRP), total isotropic sensitivity (TIS), effective isotropic sensitivity (EIS), near-horizon partial radiated power (NHPRP), and near-horizon partial isotropic sensitivity (NHPIS). If you're using an external test house for certification testing, our system can help you go fully prepared. Over-the-air measurements made in the AMS 8050 have shown good correlation to measurements made in larger, fully compliant chambers. Use the AMS-8050 Antenna Measurement System to make tests during product development, and you'll shorten the time to certification.

Data Acquisition and Analysis Software

The AMS 8050 System includes our versatile EMQ 100 Antenna Pattern Measurement Software. The software makes fully automated (pattern and frequency response) measurements for both active and passive antennas, including their vector and scalar qualities, in either transmit or receive mode.

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 Radiated Power and Near- Horizon Partial Isotropic Sensitivity required by the CTIA Over-The-Air Performance Test Plan.

Advanced graphic capabilities allow data to be shown in a variety of 2-D and 3-D formats, exported to Microsoft Excel™, PDF files or saved in Microsoft RTF format.

Special Note: The dimensions illustrated are the minimum clearances required, with a small allowance on each side to pass the system through doorways and corridors. If these dimensions are not met, the AMS-8050 may be split into two sections (System Cart, Drive Cart). Contact ETS-Lindgren Sales at the time of order if you determine there is a need to split the system.
