National Tests Wireless LANs

May 27, 2010

National Instruments is showing a new test system for IEEE 802.11n wireless-local-area-network (WLAN) testing at IMS 2010. The firm's NI WLAN Measurement Suite 2.0, which includes enhanced software toolkits for IEEE 802.11n WLAN signal generation and analysis, includes NI 6.6 GHz PXI Express multichannel RF/microwave vector signal generators (VSGs) and vector signal analyzers (VSAs). The test system can perform the phase-coherent multiple-input, multiple-output (MIMO) RF measurements required for IEEE 802.11n WLAN testing. The software-defined architecture is based on PXI modular instruments and the National Instrument's LabVIEW graphic measurement software. When combined with the latest NI PXIe-8133 quad-core embedded controller, the system can perform composite error-vector-magnitude (EVM) and power measurements in 7.0 ms.
