AMS-8500 Antenna Measurement System

AMS-8500 Antenna Measurement System

The ETS-Lindgren AMS-8500 Antenna Measurement System (AMS) packages are a series of turnkey solutions for making antenna measurements of portable wireless telecommunication devices.

The systems are fully configured to perform both research and development and type approval according to the recently published Cellular and Telecommunications and Internet Association (CTIA) test methods for portable transceivers. The system can also be used to perform antenna measurements in both near and far-field test distances for more generic antenna properties. Our system packages offer you a choice of components to fit your custom needs.

ETS-Lindgren has manufactured and installed thousands RF shielded anechoic chambers worldwide. This series of anechoic chambers is designed to have better than –25 dB in Quiet Zone (QZ) reflectivity. This will allow the user to perform antenna measurements in the QZ with less than 0.65 dB measurement uncertainty. Although standard sized anechoic chambers are listed in this package, other chambers of different dimensions can be designed to fit your specific requirements.

Rectangular chambers are available in two sizes, compact (5.5 m length) or full size (7.32 m length). The chambers are constructed with ETS-Lindgren’s Series 81 brand of RF shielding, and are lined with ETS-Lindgren’s Rantec brand of microwave absorber. The compact size chamber is designed to operate over the frequency range of 800 MHz to 6 GHz, while the full size chamber is designed to operate over the frequency range of 700 MHz to 6 GHz. The frequency range of both chambers can be extended to higher frequencies if desired.
