If import was successful, a dataset named 2450BM15A0002.s3p is now in the workspace tree
 |
- Using Parts Selector A
- 3-Port Data File (S-Parameter)
- Transformer. Parameters: Primary, Secondary, Conditioning Factor
- Center-Tapped Transformer. Parameters: Primary, Top Secondary, Bottom Secondary
|

- Double Click on 3-Port Data File Block
- Click on Advanced Option (bottom left)
- In the Simulation tab, select the “Use Dataset”radio button
- Adjust the number of ports to 3 from the drop down menu
- Ensure the Port Dataset is the 2450BM15A0002.s3p
- Verify screenshot next slide

- Should look something like this:
- Click “OK”in SP1 Properties
|
 |
- Create a variable “load_imped”
- Use ‘conj’to conjugate and implement in port 3
  |
| |
- Double Click on T2
- Change “P”value to 2 and OK out
- Double Click on T1
- Select “Use Default”for P, OK out
