  • Page 8: Chapter 1 General Information

    Introduction Welcome to the operating manual for the 3030 RF Digitizer PXI module. The 3030, when used with a 3010 Series PXI RF synthesizer module, forms a compact RF digitizer that occupies only three slots in a 3U PXI chassis.
  • Page 9 Wide bandwidth The 3030 produces a 20 MHz wide digitized IF signal. Full-rate digital IF or decimated IQ data can be output via LVDS, useful for real-time emulation. Data can also be captured to internal memory and read over the PCI bus.
  • Page 10 LVDS connector, or internal, from the internal timer or level trigger. Software The 3030 is supplied with a VXI PNP driver and soft front panel for use as a self-contained module. An instrument-level digitizer soft front panel, dll and COM object are also supplied: these allow you to use the 3030 together with a 3010 or 3011 RF Synthesizer.
