How to use S-Parameter Testbench with Simscape Electrical component

I would like to ask if it is possible to use this S-parameter Testbench to measure a circuit model.

S-parameter Testbench

Since my circuit model is built by Simscape-electrical components, I need to connect the port of S-parameter Testbench with the Simscape-electrical components, but Matlab forbidden directly connections.

Is there some components like ps-simulink converter to connect this Testbench with the circuit?

Many thanks for your help!

Hello Lu Wan,

Yes, it is possible to use the S-Parameter Testbench with Simscape Electrical components in Simulink. Here's how you can do it:

1. Start by creating a new Simulink model or open your existing model that contains the Simscape Electrical circuit you wish to analyze.
2. Drag and drop the S-Parameter Testbench block from the RF Blockset in the library browser into your model.
3. To connect the Simscape Electrical components to the S-Parameter Testbench, you'll need to use a Simulink-PS Converter block. Place this block in your model, found under the Simscape > Utilities library.
4. Connect the electrical ports of your Simscape Electrical component to the Simulink-PS Converter block. This block will convert the physical signals from Simscape to Simulink signals that can be used by the S-Parameter Testbench.
5. Set up the S-Parameter Testbench block by specifying the S-parameter data or network parameters relevant to your circuit model.
6. Execute the simulation to measure the S-parameters of your circuit model.
7. The Simulink-PS Converter is crucial for the interface between the physical network domain of Simscape and the signal processing domain of Simulink.

By following these steps, you should be able to measure the S-parameters of your Simscape Electrical model. You can look at the following documentation:

• For Simulink to PS converter: https://www.mathworks.com/help/simscape/ref/simulinkpsconverter.html.
• For Essential Electrical Modelling techniques: https://www.mathworks.com/help/sps/ug/essential-electrical-modeling-techniques.html.

I hope this helps with your simulation needs!
