Running the SOQPSK Modulator Host Model VI

This example demonstrates how to generate an SOQPSK modulated signal using NI-RFSG Script Mode.

Complete the following steps.
  1. Navigate to <LVAddons>\dltf\1\examples\Data Link Test Framework\Modems\SOQPSK\Host\Modulator and open SOQPSK Modulator Host Model.vi.
  2. Use the VST Device Name control to select the VST.
  3. Select the Modem Mode that corresponds with the demodulator that you will be running.
    • Select Continuous for an NI-RFSA-based demodulator.
    • Select Interactive for an RFmx-based demodulator.
  4. Adjust the Signal Parameters and RF Acquisition Settings to match the settings configured for the corresponding demodulator.
  5. Run the VI.
    • The front panel top-right graph displays a trellis diagram.
    • The front panel bottom-right graph displays the generated spectrum.
    • The string indicator displays the example status.
    • Use the Eb/N0 (db) control to adjust the noise added to the modulated signal on the coprocessor.
  6. Stop the example by clicking the Stop button or closing the window.
