Keysight Technologies Expands UXM Wireless Test Set LTE-A Capabilities with 4CC, 256 QAM, LTE-U, Cat 0 Support

New Enhancements Address Emerging 4G Test Challenges

SANTA ROSA, Calif. — (BUSINESS WIRE) — May 21, 2015 — Keysight Technologies, Inc. (NYSE: KEYS) today announced new enhancements to the E7515A UXM wireless test set to address leading-edge LTE-A carrier aggregation (CA) test requirements. New capabilities include support for downlink 4CC1, 256 QAM, and LTE-U with up to three unlicensed carriers, as well as FDD-TDD mixed CA and uplink intra- and inter-band CA measurements. Coupled with the UXM’s integrated, independent fading for each component carrier and cell, these advancements allow validation engineers to ensure their latest LTE-A devices will perform as expected in a true network environment.

The UXM’s large touch screen display and intuitive user interface provide easy access to complex network emulation and bring a wealth of functional test capability in an accessible stack-based environment, including support for the new 3GPP category 0 for low power, low cost machine-to-machine (M2M) devices.

Also new to the UXM is the addition of W-CDMA/HSPA+ test capabilities, enabling 3G data throughput testing with integrated fading and CPC statistics, inter-RAT mobility and handover verification, and time-aligned multi-format logging.

“We continue to leverage the potential of the powerful UXM platform to keep pace with emerging 4G test challenges, as well as address multi-format testing needs with the addition of W-CDMA/HSPA+ test and lab applications,” said Joe DePond, general manager of Keysight’s Mobile Broadband Operation. “With support for up to four component carriers, FDD-TDD mixed CA and aggregation in unlicensed bands, the UXM enables validation of today’s expanding carrier aggregation configurations to provide engineers with greater LTE-A design confidence.”

The latest UXM enhancements enable LTE/W-CDMA inter-RAT cell reselection, connected data handovers, and release with redirect in a single UXM test set, including support for CSFB and SRVCC. Validation engineers can also connect two UXMs in an array to test mobility between up to four LTE cells, and handover between LTE-A multi-carrier and W-CDMA/HSPA+ connections.

The UXM is a highly integrated signaling test set created for functional and RF design validation in the 4G era and beyond. It provides the capabilities you need to test the newest designs, delivering LTE-Advanced data rates up to 600 Mbps now and handling more complex requirements later. Assess design readiness with greater confidence with the UXM.
