Spectrum Monitoring Receiver for RF Measurements up to 7 GHz

12 November 2012 – National Instruments introduced the NI PXIe-5667 spectrum monitoring receiver to address radio monitoring, interference detection, spectrum regulation and related applications in line with ITU recommendations. The NI PXIe-5667 3.6 and 7 GHz spectrum monitoring receivers feature best-in-class dynamic range of over 110 dB and distortion performance with third-order intercept (TOI) of over 17 dBm. The instrument allows users to perform real-time signal analysis and advanced signal processing in user-configurable FPGA hardware.

Built on the award-winning, high-performance NI PXIe-5665 vector signal analyzer (VSA) architecture, the wide-band receiver is ideal for over-the-air RF measurements. Coupled with NI FlexRIO and the NI LabVIEW FPGA Module, the NI PXIe-5667 can perform real-time analysis of RF signals such as continuous spectrum monitoring, spectrogram and advanced signal processing in the FPGA hardware without the latency of moving data to and from the host controller or PC. Available LabVIEW FPGA IP include digital downconverter channelization, frequency hop detection and the ability to uncover spectrum mask violations.

 “We are extremely pleased with the performance of the NI PXIe-5667,” said Jin Bains, vice president of R&D for RF at National Instruments. “Its phenomenal dynamic range and scan rate, which is more than 10 times better than that of competing receivers, make it a game changer for radio monitoring applications.”
