   Inserting N-Port Data       

Inserting N-Port Data

To insert N-port data into the active project, follow this general procedure:

1. On the Project menu, point to Add Model and click Add NPort Model.

The N-Port Data dialog box appears.

2. Under the N-Port Data tab, type a name for the N-port in the Name text box.

3. Select an interpolation method - Linear interpolation, interpolation using a Cubic spline, or interpolation using a Rational polynomial - from the list. Your selection determines how S-parameters between frequency points in your N-port file, if needed, are calculated.

4. Specify the data source:

• Select Enter data in spreadsheet if you want to manually enter the S-, Y-, or Z-matrix data for the N-port. Then see Manually Entering N-Port Data.

• Select Import data if you want to import the N-port data file into the active project. Then see Importing or Linking to N-Port Data.

• Select Link to file if you want Designer to refer to an N-port data file during the solution process. This is useful when you want to avoid importing an N-port data file into the project every time it is updated. Then see Importing or Linking to N-Port Data.

5. Click the Port Impedance tab. If desired, change the reference impedance for the S-parameter data.

6. If desired, specify a phase rotation for the S-parameter data.

7. Click OK.

You return to the Layout window. The N-port is represented by the following symbol, which varies depending upon the number of ports.

8. Click an arbitrary point in the Layout window to place the N-port data in the project.

The N-port is listed under N-Ports in the project tree.

After inserting the N-port into the project, you must draw the connection from your model to the N-port.
