The S-Parameter Measurements Interactive Example allows you to connect a single or dual vector signal transceiver (VST) setup to perform full S-parameter measurements without interacting directly with the Pulsed RF Measurement Library API. Use the example to determine the performance of the device being tested.

The following steps provide a common user workflow for interacting with the S-Parameter Measurements Interactive Example.
  1. Launch the S-Parameter Measurements Interactive Example from the following location on your machine: C:\Program Files\National Instruments\PRFM Library.
  2. Configure your hardware settings. Refer to Configuring Hardware Settings.
  3. Configure your stimulus settings. Refer to Configuring Stimulus Settings.
  4. Configure your measurement settings. Refer to Configuring Measurement Settings.
  5. Click File»Save Configuration to store your configured parameters as a .ini file for future use.
  6. Click Connect in the menu bar to open a connection to the hardware.
  7. Click Commit in the menu bar to commit the parameters to the hardware.
  8. Click Calibrate and perform system-level calibration using the calibration wizard. Refer to Calibrating the System with the S-Parameter Interactive Example for instructions.
  9. Connect your DUT to the input ports of the couplers.
  10. Click Measure to begin the S-parameter measurement. A pop-up window opens to confirm you have connected your DUT. Click OK to confirm.
  11. View the S-parameter measurements in the display pane. Use the drop-down menus to select the traces you want to view in each quadrant.
  12. Click Log to store your measured S-parameters.
  13. Once finished, click Disconnect in the menu bar to close the hardware connection.
