Manually Entering N-Port Data

You have the option to manually enter S-, Y-, or Z-matrix data in the N-Port Data window, rather than importing or linking to an existing N-port data file.

1. From the Project menu, select Add Model > Add NPort Model to open the N-port data window.

2. Under the N-Port Data Source tab, select Enter data in spreadsheet.
3. Click the Network Data tab and select whether the information being entered is in the Time or Frequency domain on the Domain list. The Planar EM tool can interpret only frequency-domain data.
4. Select the units for the information being entered on the Units list.

• Select S-matrix, Y-matrix, or Z-matrix, depending upon the type of data you want to enter.
  Note:

  If the N-port data file contains complex propagation constant or characteristic impedance values, select Gamma or Z_o, respectively, to view the data, but the information is not appropriate to run a simulation.

5. Enter the number of ports to which the N-port is connected in the Ports box.
6. Select the format in which you want to enter the data - (magnitude, phase), (real, imaginary), or (dB/, phase) - on the list. Then enter the data for each frequency point in the spreadsheet.

• Click Add Frequency to add information for an additional frequency point.
• Click Clone to create a copy of the selected set of frequency data and place the copy at the end of the spreadsheet. Cloning can save data entry time.
• Click Delete to delete the selected set of frequency data.

7. Follow the general procedure for inserting N-Port data.
