ZigBee, Wi-Fi test and analysis solutions

Supplier News

NATIONAL Instruments collaborates with software providers to deliver complete RF/communications test and analysis solutions based on modular hardware and software. To test compliance of IEEE 802.15.4 WPAN (ZigBee) and IEEE 802.11 (Wi-Fi) applications, engineers can use SeaSolve Software tools that integrate with NI PXI-based RF hardware and the LabVIEW graphical development environment for a flexible and cost-effective solution.

The platform is built on the PXI standard, providing a foundation to develop a complete test system. Using National Instruments’ LabVIEW and the modulation toolkit for LabVIEW, engineers can develop customised measurement systems to address a variety of RF standards. Companies have worked with NI to build standards-based test systems on this platform for testing WPAN, Wi-Fi and GSM. Other standards-based systems are currently under development.

SeaSolve recently developed a compliance test software solution for the ZigBee and Wi-Fi standards that integrates with the NI PXI-5660 vector signal analyser, the NI PXI-5670 and PXI-5671 vector signal generators and the NI Modulation Toolkit for LabVIEW. With this software, engineers can perform the physical-layer RF tests specified by the standard on their devices with pass/fail results. These tests range from transmit centre frequency tolerance and receiver sensitivity to symbol rate and maximum input power. Because the solution is based on modular hardware, engineers save significant time and costs developing their test systems and reusing the same instruments for testing various standards. In addition, SeaSolve engineers are currently exploring IEEE 802.16 WMAN (WiMAX) compliance testing solutions with LabVIEW and NI RF hardware and software.
