S-Parameter Fitter

Convert S-Parameter network to impulse response

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.
