ETS-Lindgren announces Test System for Wireless Over-the-Air Measurements on mobiles, laptops and Machine to Machine Communication equipment
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 700 MHz to 18 GHz.
The AMS-7000 is based on a combination of ETS-Lindgren’s industry leading EMQuest™ Antenna Measurement Software and the company’s longstanding line of SMART™ reverberation chambers. By using EMQuest software, the AMS-7000 is able to support a broad range of protocols and instrumentation readily available for other AMS series OTA measurement systems.
The compact chamber is mounted on wheels and is ideal where space is limited or where a portable test solution is needed and detailed antenna pattern data is not required. Test subjects with dimensions up to 0.9m x 0.9m x0.6m are supported.
Bryan Sayler, Senior Vice President, Test Solutions at ETS Lindgren commented, “ETS-Lindgren offers the broadest range of technologies and options for performing Over-The-Air measurements of wireless devices. Our 20 years of experience with statistical reverberation measurements allows us to provide our customers with an additional alternative to our well-established anechoic solutions.”
ETS-Lindgren is the world’s largest provider of integrated solutions for wireless, electromagnetic compliance (EMC), microwave, and acoustic measurement systems. ETS-Lindgren has built more than 80% of CTIA Over the Air test labs world-wide and was also the world’s first CTIA CATL (CTIA Authorized Test Lab)
