S-Parameter Fitter

Convert S-Parameter network to impulse response

Since R2021b

Description

The S-Parameter Fitter app creates a SParameterChannel object which combines a scattering parameter (S-Parameter) model of a baseband communication channel with an analog transmitter and receiver into a single S-Parameter, with adjustable port ordering. There must be at least 4 ports. The app then calculates an impulse response of the S-Parameter using the rational (RF Toolbox) function from the RF Toolbox™.

Using the app, you can:

• Set the maximum number of poles, error tolerance, transmitter amplitude, rise time and RTF factor, and the resistor and capacitor values.

• Plot the impulse response before selecting it for channel model.

Open the S-Parameter Fitter App

• MATLAB^® command prompt: Enter sParameterFitter.

• SerDes Designer app: Open the Analog Channel block parameters dialog box and click the Import S-Parameter button.

• Simulink^® model: Open the Analog Channel block parameters dialog box and click the Import S-Parameter Touch File... button.

Examples

• Convert Scattering Parameter to Impulse Response for SerDes System
