"We are excited about this new RF and functional test capability for the UXM platform," said Joe DePond, general manager of Keysight's Mobile Broadband Operation.

"Coupled with the UXM's current downlink carrier aggregation, integrated fading and flexible receiver test capabilities, this new functionality demonstrates the UXM's ability to handle the challenging 4G test requirements of next-generation handsets and devices."

The UXM is an industry-leading wireless test set with a breakthrough system architecture and versatile touch screen. The UXM is a highly integrated signaling test set created for functional and RF design validation in the 4G era and beyond.

Features:

－ Uplink carrier aggregation support, enabling sustained bidirectional 300 Mbps/100 Mbps end-to-end IP data throughput.

－ Expanded functional test capability with support for VoLTE (including semi-persistent scheduling, multi-DRB and TTI bundling), handovers (including CSFB and SRVCC), connected mode DRX (for battery drain analysis), and in-depth protocol logging with new Wireshark-based logging software.

－ Integrated X-Series measurement applications for RF design performance verification. The X-Series applications deliver trusted measurement science, a consistent user interface with the ability to troubleshoot and analyze issues using the X-Series' flexible measurement control.
