Touchstone Data Format

Touchstone data files contain S-, Y-, Z-, H-, or G-parameter data for a single device. The data file typically contains information about the device type and measurement conditions followed by sequential data lines. Touchstone® is a registered trademark of Agilent Technologies, Inc.

The Circuit solver supports both Version 1.1 and Version 2.0 of the Touchstone specification.

Touchstone® File Format Specification, Rev 1.1, Copyright© 2002 by the EIA/IBIS Open Forum.
Touchstone® File Format Specification, Version 2.0, Copyright© 2009 by TechAmerica.

Note:

The Circuit solver does not support the Mixed-Mode N-Port Parameters in the Touchstone 2.0 Specification.

See Circuit S-Parameter Technical Notes for details on how the Circuit solver handles Touchstone files.
