Keysight Technologies Accelerate Development of Next Generation 802.11ac Wireless LAN Transmitters-Overview Application Brief Achieve increased insight into chipsets and modules for enterprise wireless set top boxes, mobile computing, and medical devices with measurement solutions for R&D and design verification test (DVT) of 802.11ac transmitters Abstract Application overview Wireless video and wireless data networking are driving Design validation engineers must ensure their 802.11ac demand for standards, such as 802.11ac, which enable higher designs will perform well under a variety of conditions, throughput. Design validation engineers must ensure their validating that their devices meet performance requirements 802.11ac designs will perform well under the most demanding even for the most challenging MIMO spatial multiplexing modulation schemes, including MIMO spatial multiplexing modes. To validate MIMO transmitter performance, a multi- configurations. channel signal analyzer can be used to demodulate the multi- stream waveforms and measure EVM and other physical To validate MIMO transmitter performance, a multi-channel layer parameters. signal analyzer can be used to demodulate the multi-stream waveforms and measure EVM and other physical layer param- Design and validation of 802.11ac MIMO transmitters eters. The Keysight Technologies, Inc. PXI signal analyzer requires making EVM measurements of multi-channel MIMO solutions enable MIMO 802.11ac R&D and test engineers spatial-multiplexing signals. A test solution should be able to to validate their designs with a mixture of measurement make these measurements rapidly, and with a high degree of accuracy, fast speed, flexibility and scalability in a small form confidence. The higher-order modulation formats and wider bandwidths proposed in the 802.11ac standard require better factor. EVM, and the test solution's residual EVM should be able to exceed these requirements and enable future modifications For measurements you can trust, with a modular, scalable to the designs as they evolve, from single- and dual-channel design for easy upgradability, Keysight's PXI modular software 40 MHz to 3- and 4-channel 160 MHz MIMO designs. and hardware solutions make 802.11ac validation easy.
