Extract text from Touchstone 2-port data files (S2P)
To convert S2P Touchstone files to another format, you need Keysight ADS or other Data software.
To convert other file formats to the "Touchstone Data File" file type, you need software like Keysight ADS or a similar tool.
.S2P files primarily contain Scattering Parameters (S-parameters) for 2-port electrical networks. Engineers use them to describe how RF (Radio Frequency) and microwave components, like amplifiers or filters, reflect and transmit signals across different frequencies. They follow the Touchstone file format standard. A secondary, much rarer use is for the Songs2See educational music game developed by Songquito.
These engineering files are usually generated by Vector Network Analyzers (VNAs) such as the popular open-source NanoVNA, or enterprise testing equipment from Rohde & Schwarz and Keysight Technologies.
The main disadvantage of the .S2P format is its highly specialized nature. While it is technically a plain text file, the matrix syntax (frequency, magnitude, and phase or real/imaginary parts) is impossible for humans to visualize without specialized tools. Proprietary RF simulation software is extremely expensive and often tied to restrictive corporate licenses, making it difficult to share S-parameter data with non-engineers or clients who lack the software.
To make this data useful outside of the lab, convert .S2P to CSV or XLSX. This strips the proprietary formatting and lets you manipulate the raw numbers in standard spreadsheet tools. For reporting or archiving, convert plotted data to PDF or PNG.
Convert.Guru analyzes your S2P file, detects the exact format, and lets you read the text inside.
Users also converted S1P, TXT, SLDPRT, S4P and XPT files.
If you want to convert S2P file to , you can use Keysight ADS or similar software from the "2-Port Network Parameter Storage" category. In the File menu, look for Save As… or Export….
To convert files to S2P, try Keysight ADS or another comparable tool in the "2-Port Network Parameter Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our S2P converter.
