Data Import

Touchstone data files, network parameter data entry, AMP files

Using RF Toolbox™ functions and classes to read data and generate network parameters or network objects from industry-standard Touchstone files (.s2p, .y2p, .z2p, and .h2p) and AMP files, a MathWorks® file format.

To learn how to import and create networks, see Create and Import Circuits.

To understand how this toolbox represents S-parameters and AMP files, see S-Parameter Notation and AMP File Data Sections.


RF Toolbox does not support Touchstone 2.0 files.
