Creating an N-Port Model with No File

N-port frequency-dependent data such as S-parameters can be entered manually instead of reading it from a file. To create an N-port element to receive manually entered data, select the Circuit project that contains it.

1. View the Component Libraries area, select the Symbols tab. Click Import Models.
2. Select the NPort_NoFile icon to open the N-port data window. The Mode is set to Enter data in spreadsheet.

   

3. Click Network Data tab.

   

   The Network Data tab is used to view the data from an imported file, or to enter the N-port data manually.

• Domain – Selects the Frequency or Time domain.
• Format – Selects the Format to one of the following: Magnitude/Phase, Real/Imaginary, or dB Phase.
• Units – From the Frequency domain, selects the units of frequency: Hz, KHz, MHz, GHz, THz, or rps. From the Time domain, selects the units of time: fs, ps, ns, us, ms, or s.
• S Matrix – Identifies the data as S-parameter values
• Y Matrix – Identifies the data as Y-parameter values
• Z Matrix – Identifies the data as Z-parameter values
• Gamma – Identifies the data as Gamma values
• Z0 – Identifies the data as Z0 values
• Ports – Sets the number of signal ports
• Phase Rotation — Click to set the Phase Rotation of the N-Port Network Data source.The Noise Data and Options tabs are the same as for the file-based N-port. See Editing an N-Port Model.

4. Click OK. An instance of the N-Port is attached to the cursor so drag and drop it in the schematic.
