Scattering parameters, or S-parameters, are the most common network representation in RF/microwave engineering. In recent years, as the digital circuits are operating in the giga-hertz realm, S-parameters become popular in most areas of electrical engineering. The tool here is an S-parameter plotter and viewer. The utility anwsers the needs of viewing, and common manipulations, of S-parameters. To get a peek at the tool, click the link to the screen shots of the main application, as well as several example plots: Plot-1, and Plot-2. Here are some of the features offered by the tool:
- Read data from Touchstone or CITI files
- Derive Y, Z parameters for given S-parameters
- Perform mixed-mode conversion
- Write S-parameters to files
- Plots of S-parameter values (magnitude, phase, db, real or imaginary parts)
- Export plots to vector-based graphic formats (EPS and SVG)
- Export plots to raster graphic formats (PNG, JPG)
- Export plot data to ACSII files
More detailed descriptions are available in the user's guide. Please read the license agreement before downloading. The current distribution has an expiration date of March 30, 2008. After that date, the application will impose a restriction of allowing only one curve per plot. For academic users, EE Circle offers a free license (that will retain full functionalities) upon request.
