The ETS-Lindgren Model 8050 Antenna Measurement System is compact, fully anechoic RF enclosure for antenna pattern measurements. The AMS-8050 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

Small in size but big on operational throughput, the AMS 8050 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 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.
