Visualization and Data Export

Visualize RF data using Smith charts, polar, and Cartesian plots; save Touchstone files

You can use RF Toolbox™ functions to visualize component or network behavior:

  • Smith® Chart

  • Rectangular plots

  • Polar plots

You can also create charts and plots using The RF Design and Analysis Tool.

The RF domain uses many types of data files, including industry-standard Touchstone files (.s2p) and AMP files, a MathWorks® nonlinear file format. You can write data into these files using several different RF Toolbox functions.

You can also export a network to Verilog-A format for use as a test environment in an analog circuit simulator. See Export a Verilog-A Model.

Note

RF Toolbox does not support Touchstone 2.0 files.
