Perform tuner auto de-embedding

You can only start this task if you started one of the procedures in part CW mode B-HF characteristics or Pulsed mode B-HF characteristics. For more details, see Tuner auto de-embedding.

  1. Load tuner initialization
    Click on Yes if the load tuner is not at initial position.

  2. Hardware configuration check
    All the measurement hardware needed for tuner auto de-embedding must be correctly set. If so, all hardware is marked with . Then, click on .

    Note: The calibration wizard reminds you to check the 10 MHz signal configuration between external signal generator and VNA.
  3. Calibration settings
    Set the power level and select the frequencies to apply de-embedding. Then, click on .

  4. Bench configuration
    Connect the measurement bench as shown in the following figure and click on to perform measurement.

  5. Intermediate results
    After the measurement, the Smith chart present the maximum gamma available before and after the de-embedding for each selected frequency. The blue circle represents the maximum gamma at the tuner calibration plane and the red circle represents the maximum available gamma achievable at the calibration reference plane. Click on to perform measurement to continue.

  6. Load tuner initialization
    Click on Yes if you want to put the load tuner at the initial position.

  7. Final results
    By clicking on , VISION will create a fixture file with s2p extension and a termination file with s1p extension. These newly created files will be displayed in Setup > File Manager. Select Install generated de-embedding files option to transfer automatically these files from File manager to the load tuning station settings in Setup > Schematic.
    Figure: Final results


  8. File manager
    Click on Setup > File Manager to find the files created by the tuner auto de-embedding wizard.

  9. De-embedding
    To check that the files are properly placed in the load tuning station, click on Setup > Schematic > Load Tuning Station > Passive Tuner > De-embedding. The fixture file and the termination file are in the corresponding fields for proper de-embedding.
