Agilent Technologies Inc. has enhanced its Vector Signal Analyser (VSA), Signal Studio and Mobile WiMAX Test Set measurement solutions to facilitate testing of the WiMAX Forum's Wave 2 system profiles.

The standardised profiles specify options such as multiple input multiple output (MIMO), a capacity enhancing multi-antenna technology fundamental to mobile WiMAX. With their ability to accurately and cost-effectively test MIMO and other Wave 2 profile functionality, Agilent's enhanced measurement solutions provide the most up-to-date tools for engineers requiring signal analysis, signal generation and end-to-end functional test of mobile WiMAX.

The ability to test Wave 2 system profiles is crucial to the successful deployment of mobile WiMAX products. Agilent's 89601A VSA and N7615B Signal Studio measurement solutions address this need via a range of new test capabilities that support PHY layer signal generation and analysis for Wave 2 system profiles. Specific capabilities include matrix A and matrix B signals for downlink, uplink collaborative MIMO, and creation of HARQ bursts and uplink sounding zones. N7615B Signal Studio also provides MIMO fading embedded in a waveform. This capability enables testing of MIMO receivers without the added expense of fading hardware or software. Together, these features make the Agilent 89601A VSA and N7615B Signal Studio key tools for R&D engineers working in mobile WiMAX development.

In addition, the Agilent E6651A Mobile WiMAX Test Set incorporates flexible base station emulation, IP traffic support and a unique ability to make on-board RF parametric measurements in one integrated unit. The set does require external equipment to measure UL signals. The E6615A's Wave 2 enhancements include support for DL, STC, SM and UL collaborative MIMO measurements. It also offers the protocols to support operating with the DUT in MIMO modes.

Furthermore, Agilent N7615B Signal Studio software for 802.16 WiMAX is used to create 802.16e waveforms for PHY layer testing. It supports the ESG, MXG and PSG signal generators. Agilent's 89601A VSA is a PC-based software package designed to measure the RF and modulation quality of most digitally modulated signals. It features a large array of demodulators, filters, displays and analysis tools.

"The Wave 2 and MIMO functionality provided in these new releases is further evidence of this commitment. As a result, our measurement solutions not only help engineers move forward with their development efforts, but also help move forward the successful evolution and deployment of mobile WiMAX," said Agilent's Guy Sene, VP of marketing, wireless business unit, and VP and general manager, signal analysis division.

Support for Agilent's MIMO and Wave 2 features is now available as part of the Agilent N7615B Signal Studio. These features will also be supported in future updates to the 89601A VSA and E6651A. Availability for these products is expected in September 2007 and year-end, respectively. Pricing is available upon request.
