Can i use several channel modules to simulate S-parameter by Serdes Toolbox in Simulink?

Now i want to simulate a Serdes system (mainly receiver). Meanwhile i attempt to insert some S-parameter module to simplify the whole system modeling but there is no S-parameter module in Serdes Toolbox, so i want to use existing channel module to import S-parameter.

For example, I put a channel module between Tx and Rx regarded as 'channel' and I also put a channel module in Rx (or after Rx?) regarded as other loss models (by importing S-parameter). Is it ok? Or there is other module can import S-parameter and use in Serdes system?

Hi Ruixian,

I understand that you want to import S-parameters to use them in a Serdes system.

To use S-Parameters from a Touchstone file as your channel model if your channel model is set to Impulse response, click the Import S-Parameter model button. You can modify the maximum number of poles, error tolerance, transmitter amplitude, rising time, and RTF factor, as well as the values of the resistor and capacitor, using the S-Parameter Fitter dialogue box that appears. The impulse response can also be plotted before being chosen for the channel model.

Please refer to the following documentation link for more information:

Hope it helps!!
