Keysight Technologies, Inc. today announced two additions to its Signal Studio software suite of signal creation tools. The first is signal generation software for the IEEE 802.15.4g-based Wi-SUN standard. The second is support for LTE/LTE-Advanced uplink (UL) 2x2 MIMO with real-time Hybrid Automatic Repeat Request (HARQ). These new capabilities further ease the signal generation requirements for R&D and manufacturing engineers developing or testing the conformance of devices to the Wi-SUN and LTE/LTE-A standards. “As a recognized industry leader in electronic measurement, Keysight is actively involved in the development, revision and implementation of emerging standards like Wi-SUN and LTE-Advanced,” said Satish Dhanasekaran, marketing manager of Keysight’s Microwave and Communications Division. “Keysight’s new Signal Studio software capabilities complement our comprehensive portfolio of standards-based signal-generation and analysis solutions, and reaffirms our commitment to providing designers with the world-class solutions they need to move their standards-based designs forward.” N7610B Signal Studio Keysight’s new N7610B Signal Studio software generates Wi-SUN signals and supports the MR-FSK and MR-OFDM Wi-SUN modes. A fully coded advanced capability allows the software to easily make receiver conformance tests using Keysight signal generators (e.g., MXG/EXG, PSG/ESG or PXIe). For a more complete R&D and manufacturing solution, the N7610B can be used with Keysight signal analysis tools. Such functionality and flexibility make the N7610B well suited to support the needs of the emerging market for smart utility networks (e.g., smart grid) in Japan and those companies in the U.S. working on Wi-SUN-based solutions and products. Based on the open global IEEE 802.15.4g-2012 standard, Wi-SUN is intended to advance and enable interoperable and reliable, cost-effective, low-power, wireless utility products for wireless smart utility networks and related applications. The 802.15.4g PHY carries multiple data rates in frequency bands from 450 MHz to 2.4 GHz and operates in three modes: 1) multi-rate multi-regional frequency shift keying (MR-FSK); 2) multi-rate orthogonal frequency division multiplexing (MR-OFDM); and 3) multi-rate multi-regional offset quadrature phase shift keying (MR-OQPSK).
