Running the Pulsed BPSK Modulator Model VI

This example demonstrates how to generate a Pulsed BPSK modulated signal using NI-RFSG Script Mode.

Complete the following steps.
  1. Navigate to <LVAddons>\dltf\1\examples\Data Link Test Framework\Modems\Pulsed BPSK\Host\Modulator and open Pulsed BPSK Modulator 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 the constellation.
    • The front panel bottom-right graph displays the generated waveform.
    • 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.
