Creating and Optimizing 802.11ac
Signals with the M8190A AWG
Application Note
Introduction
The new IEEE 802.11ac wireless LAN standard aims to provide higher data throughput rates of over
1 gigabit per second, to improve the user experience and to enable new applications, such as
transmission of multiple streams of high-deinition multimedia data. To achieve these data rates, the
Very High Throughput (VHT) physical layer speciication has introduced new features, including wider
bandwidth channels of up to 160 MHz and 256 QAM modulation.
802.11ac devices will need to meet more stringent speciications for RF performance, especially for
error vector magnitude (EVM) over wider bandwidths, so it is important to have test tools that provide
the best reference signals and EVM measurements, particularly for R&D and design validation.
This application note details how to create and optimize 802.11ac signals using the N7617B Signal
Studio for WLAN 802.11a/b/g/n/ac software with the Keysight Technologies, Inc. M8190A Arbitrary
Waveform Generator (AWG) to get the highest quality signals from the instrument. This application
note is based on the application note Creating and Optimizing 802.11ac Signals and Measurements,
Literature number 5991-0574EN, which also includes the analysis of 802.11ac signals using the
N9030A PXA signal analyzer and provides hints for achieving the best EVM measurements with this
solution.
