Vaisala Sigmet Digital Receiver and Signal Processor RVP900

The Vaisala Sigmet Digital Receiver and Signal Processor RVP900™ - Dual Polarization, Wide Dynamic Range, and Pulse Compression ready
    Overview

     Overview

    • The RVP900™ Sigmet Digital Receiver and Signal Processor provides comprehensive digital IF and signal processing functions on an open Linux PC platform
    • 100 MHz, 16-bit IF sampling improving sensitivity and dynamic range in 5 independent channels
    • 38.4 Billion multiply accumulates cycles per second which is a x5 increase over the RVP8™
    • RVP900™ Sigmet is compatible with any PC server using a Ethernet interface. The next generation hardware is the next faster PC chip.
    • Independent and parallel FIR filtering allowing dual pulse width and dual frequency strategies on each receive channel
    • Dual Polarization, Wide Dynamic Range, and Pulse Compression ready
