Decoder hardware and software ( W-CODE )
Prepared for protocols and systems requiring two concurrent channels (like the currently implemented FAX & Modem protocols).
Together with W-PCIe, W-PCI constitutes the latest member of the WAVECOM family of decoders and replaces W-61PC.
W-PCI is an input device for W-CODE and is fully routable via its host system.

  • W-PCI and W-CODE are delivered as a package
  • W-CODE input device
  • PCI-Slot signal acquisition hardware for 2 channels (IF70 MHz or AF/IF 50 Hz to 25 MHz))
  • A/D conversion
  • Digital Down Conversion (DDC)
  • Decimation
  • Filtering
  • 5 selectable inputs (3 x IF70 MHz, 2 x AF/IF)
  • Typical applications:
    • HF/VHF/UHF monitoring using the AF/IF input (superior to a sound card)
    • INMARSAT-monitoring, using a down converter with 70 MHz IF output (L-Band or C-Band)
