To develop and use an FPGA VI with the NI 5641, you must complete four major steps.

  1. Create the LabVIEW project.
  2. Add the hardware target.
  3. Develop and compile the FPGA VI.
    Note You can develop the FPGA VI using either the traditional LabVIEW FPGA method or the NI-5640R Asynchronous Programming palette.
  4. Create the host VI to communicate with the target.

Simple Spectrum Analyzer Example

The following sections walk you through creating a simple spectrum analyzer using one of the analog input channels on the NI 5641. You can configure the center frequency and the bandwidth to analyze. The application also generates a sine tone that can be used as the signal to analyze.
