The tschk2 program is the official parser for the Touchstone 2.1 specification. Standalone executables are provided free of charge by the IBIS Open Forum. Contact tschk@ibis.org for information or to report bugs. You must download these in a manner allowing you to run the executables with required command line arguments. No installer is provided.

Each link below will download a zip archive containing the selected executable(s) as well as the license agreement file, which must be copied along with the executables in any redistribution. Executables for tschk2 are available for the following platforms:
The full set of executables is available in one ZIP archive tschk210_all.zip.
NOTE 1: Compliant Touchstone files must be ASCII encoded. It has been found that redirecting the output of tschk2 in Windows PowerShell to convert file formats will result in Unicode files, which will fail a subsequent tschk2 check. On Windows, cmd or cygwin shells are recommended for executing tschk2.
NOTE 2: The executable files are not digitally signed. Steps may be required in your operating system to allow them to run.
SHA1 digests are shown below for checking the integrity of each official executables above. Unzip the contents of the ZIP file(s) and save the SHA1 checksum file tschk210_sha1.txt (contents shown below). Then run "sha1sum -c tschk210_sha1.txt". The report for each file should be "ok" (may need Unix, Linux, or Cygwin):

When “tschk2” is run with the -help argument, TSCHK2 prints this help message:
tschk2, version 2.1.0 verification tool for Touchstone v2 files Usage modes: tschk2 FILE Checks the file, sending error and warning information to stderr. tschk2 -canonicalFILE Shortcut for -canonical-v2. tschk2 -canonical-v2 FILE Checks the file, sending error and warning information to stderr, and writes a valid file to stdout in Touchstone v2.0 or V2.1 format. tschk2 -canonical-v1 FILE Checks the file, sending error and warning information to stderr, and writes a valid file to stdout in Touchstone v1.0 or V1.1 format, if possible. tschk2 -describe FILE Checks the file, sending error and warning information to stderr, and writes a valid file to stdout in a long-form description. tschk2 -version Displays the version number. tschk2 -help Displays this help message. Canonical output options: -freq-precision freqDigits Set precision of frequency column in canonical network parameters output. Set to 0 to calculate precision based on precision of inputs. Default: 15 digits -data-precision dataDigits Set precision of data columns in canonical network parameters output. Set to 0 to calculate precision based on precision of inputs. Default: calculate precision from inputs -spacing aligned|compact Set spacing to 'aligned' to produce output with network parameter values arranged in aligned columns. Set spacing to 'compact' to produce output with minimal length network parameter values, separated by single spaces. Default: aligned
One (and only one) file name argument must be provided to perform checking. Examples of output using different output options are available here.
Version 2.1.0 of tschk2 supports Touchstone 2.1, 2.0, 1.1 and 1.0.
