Data Import and Network Parameters

Read Touchstone files; import, manipulate, and convert network parameters such as S-parameters

Use RF Toolbox™ functions to read RF data and use network parameters created from industry standard Touchstone files (.s2p, .y2p, .z2p, and .h2p).

To understand how this toolbox represents S-parameters, see S-Parameter Notation.

You can convert multi-port network parameters among different formats (S, Z, Y, H, G, T, ABCD). For example, Y-parameters are convenient for working with RLC circuits, whereas S-parameters are better for visualizing frequency responses.

You can also convert single-ended S-parameters to mixed mode S-parameters, extract M-port S-parameters from N-port S-parameters or change the characteristic impedance.

To learn what you can do with network parameters, see RF Network Parameter Objects.

Note

RF Toolbox does not support Touchstone 2.0 files.

De-Embedding S-Parameters

De-Embedding S-Parameters

Extract the S-parameters of a Device Under Test (DUT). First, read a Touchstone® file into a sparameter object, calculate the S-parameters for the left and right pads, de-embed the S-parameters using the deembedsparams function and then display the results.

RF Data Objects

RF Data Objects

Manipulate RF data directly using rfdata objects. First, you create an rfdata.data object by reading in the S-parameters of a two-port passive network stored in the Touchstone® format data file, passive.s2p. Next, you create a circuit object, rfckt.amplifier, and you update the properties of this object using three data objects.
