A Touchstone file (or .snp file) is a standard ASCII text format used by RF engineers to document the n-port network parameters, such as S-parameters, of linear devices. While these files can be opened in simple text editors, specialized options are essential for transforming raw data into visual charts, Smith charts, and analytical reports.
