ETS-Lindgren has introduced a test system for wireless over-the-air (OTA) measurements employing reverberation technology. The new AMS-7000 performs accurate and repeatable wireless measurements on wireless devices such as mobile phones, laptops and machine-to-machine communication (M2M) enabled equipment.
As an alternative to anechoic chambers, ETS-Lindgren’s new AMS-7000 test system uses reverberation technology for making a variety of accurate and repeatable wireless over-the-air (OTA) measurements. The results have shown correlation to CATL (CTIA Authorized Testing Laboratory) results. Tests that can be performed include SISO (Single In, Single Out), TRP (Total Radiated Power), TIS (Total Isotropic Sensitivity) and MIMO (Multiple In, Multiple Out) throughput measurements. The test system incorporates two Z-fold tuners, a DUT turntable and an antenna turret to improve isotropicity and homogeneity. The system operates over a frequency range of 700MHz to 18GHz.
The AMS-7000 is based on a combination of ETS-Lindgren’s EMQuest Antenna Measurement Software and the company’s longstanding line of SMART reverberation chambers.
