Convert S1P to another file type

To convert S1P data files to another format, you need Keysight ADS or other Data software.

Convert a file to S1P

To convert other file formats to the "Touchstone S-parameter File" file type, you need software like Keysight ADS or a similar tool.


About S1P files

The .s1p file is a standard ASCII text file formatted using the Touchstone specification. It is primarily used to store 1-port network parameter data, specifically Scattering parameters (S-parameters). These files are typically generated by Vector Network Analyzers (VNAs) manufactured by companies like Keysight Technologies, Rohde & Schwarz, or the open-source NanoVNA platform.

The main disadvantage of the .s1p format is that it is strictly a raw data container. It stores columns of frequency, magnitude, and phase (or real/imaginary values), but lacks any built-in visualization. You cannot see an RF reflection graph, a return loss plot, or a Smith chart without importing the file into specialized, expensive RF simulation software like Keysight Advanced Design System (ADS). Additionally, regular spreadsheet tools often struggle to import it cleanly because it relies on complex space-delimited columns and a specific # option header, rather than standard commas.

To make the data accessible, the most practical conversion targets are CSV or XLSX. Converting to these standard tabular formats allows engineers to easily parse, filter, and graph the data in Microsoft Excel or Python without needing dedicated RF tools.

Because this file format contains highly specialized mathematical parameters, generic online document converters cannot process or visualize S-parameter RF data.

Convert.Guru analyzes your S1P file, detects the exact format, and lets you read the text inside.

Users also converted S2P, CSV, TXT, S4P and WF1 files.


FAQ

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 S-parameter 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 S-parameter 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.
