National Instruments announces three new products that extend high-speed data acquisition and data streaming into RF and communications applications. With the new RF vector signal analyzer and two new IF digitizers that include advanced FPGA-based signal processing, engineers can continuously stream high-bandwidth RF data across high-speed buses directly to a PC for processing and analysis. The PXI-5661 2.7 GHz RF vector signal analyzer features 20 MHz of real-time signal or modulation bandwidth, frequency-selective burst triggering and onboard signal processing for streaming data to a PC at full bandwidth. The analyzer implements an onboard quadrature digital downconverter in an FPGA to reduce the amount of data to transfer to the host PC so that high-bandwidth RF signals can directly transfer across the high-speed PXI backplane. NI 5142 communications digitizers are the IF components of the NI PXI-5661 analyzers and are available separately in PXI or PCI for addressing a broad set of IF applications.
