RF Network Parameter Objects

Overview of Network Parameter Objects

RF Toolbox™ software offers network parameter objects for:

Importing network parameter data from a Touchstone file.
Converting network parameters.
Analyzing network parameter data.

Unlike circuit, model, and data objects, you can use existing RF Toolbox functions to operate directly on network parameter objects.

Available Network Parameter Objects

The following table lists the available network parameter objects and the functions that are used to construct them. For more information on a particular object, follow the link in the table to the reference page for that functions.

Network Parameter Object Type	Network Parameter Object Function
ABCD Parameter object	`abcdparameters`
Hybrid-g parameter object	`gparameters`
Hybrid parameter object	`hparameters`
S-parameter object	`sparameters`
Y-parameter object	`yparameters`
Z-parameter object	`zparameters`
