AT4 wireless has unveiled the T4010 LTE RF test system, a complete and cost-effective platform to perform RF parameter verification throughout the development life of LTE-enabled user equipment (UE).

The T4010 targets the R&D testing segment in chipset manufacturers and UE developers, as well as certification laboratories. The test system gives engineers full verification and validation capabilities for the RF transceiver of the LTE UE, allowing not only customization of 3GPP defined RF test cases, but also complete test case development and full control of the test system.

The T4010 is based on the E2010 broadband wireless test set, an expandable hardware platform that minimizes the operating costs and the amount of instruments needed in the system. The E2010 is the cornerstone of all AT4 wireless LTE testing products.

The test system also features additional testing software and provides 2x2 multiple input multiple output, embedded measurement capabilities, integrated interferer generation and channel emulation. For tests requiring an extended frequency range, the E2010 can be connected to a wide array of commercially available instruments allowing the reuse of already purchased equipment, thus minimizing the involved acquisition costs.

Existing MiNT T1140, T1150/52 and T2110, AT4 wireless' RF test systems for 2G, 3G and WiMAX, can be seamlessly upgraded to support LTE with minimal system downtime and retaining all the functionalities already present in the MiNT system.

The T4010 is designed to minimize testing time, obtaining several measurement results from a single capture. It also provides a high level of automation, managing test campaigns of several UEs in sequence. The applications supported by the T4010 cover all aspects of RF testing: functional block verification, RF parametric testing, margin search, RF performance testing and complete system validation and certification, including type approval.

"Today, AT4 wireless is leveraging its extensive experience in wireless test system manufacturing and introducing an innovative approach in the RF testing field. The T4010 LTE RF test system one box solution provides the complete set of RF testing capabilities currently requiring expensive multi-instrument systems, in a convenient and cost effective single instrument platform. The ability to develop completely customized RF test cases will cover a key need when developing a LTE UE. Besides, supporting 3GPP test cases paves the way to use this test system for GCF and PTCRB certification testing," stated Juan Hidalgo, LTE product manager at AT4 wireless.

AT4 wireless has also announced LTE test Systems for PHY and protocol stack, and will continue developing LTE test solutions and contributing to the LTE worldwide deployment.
