Convert S1P to another file type
To convert your S1P file to another format, you need Keysight ADS or other Data software.
Convert a file to S1P
To convert other file formats to the "RF Engineering Data" file type, you need software like Keysight ADS or a similar tool.
About S1P files
A .s1p file is a specialized data container known as a Touchstone file, used primarily in Radio Frequency (RF) engineering to store 1-port Scattering parameters (S-parameters). These files contain ASCII text data representing frequency, magnitude, and phase information, often generated by vector network analyzers (VNAs) from companies like Keysight Technologies and Rohde & Schwarz. While the file is human-readable text, the raw columns of complex numbers are difficult to interpret without visualization tools like Smith Charts or Log-Magnitude plots. Engineers often face challenges when trying to share this data with non-technical stakeholders or when attempting to analyze it in standard spreadsheet software, as the header formats and numbering conventions (Real-Imaginary vs. Magnitude-Angle) vary. To overcome these limitations, users frequently convert .s1p files to CSV or XLSX for easy manipulation in Microsoft Excel, or to PDF and PNG to archive the visualized measurement curves for reports.
Convert.Guru analyzes your S1P file, detects the exact format, and lets you read the text inside.
If you want to convert S1P file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Keysight ADS or similar software from the "RF Measurement Data Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to S1P, try Keysight ADS or another comparable tool in the "RF Measurement Data Storage" category.
The S1P Converter Story
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 S1P converter.
