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.
