Touchstone Viewer

What is a Touchstone?
Originally a file format type of a circuit simulator by EEsof, the touchstone file format had since become a universal file type used for the documenting of the behavior and response of the network parameter (a.k.a. S-Parameters) of a device. It is also sometimes called SnP files which is derived from its file extension (.snp) with the n being the number of ports of the device documented. Y-Parameters and Z-Parameters can also be written in the touchstone format with the file extension of .ynp and .znp respectively, albeit not as common as the more commonly used .snp type.

How do I view a Touchstone file?
A touchstone file is written in the ASCII text format (which means you can view its raw data using notepad or similar text editor apps). Each line in the file correspond to the data of all parameters at a single frequency point.

To view the whole response, one would need a software that is able to read the ASCII file and translate them into a meaningful graph or chart.
