S-View is a free S-parameter viewer; It allows you to view the data of the s-parameter or the scattering parameter which is used to characterize RF/Microwave components and systems. The S-View supports the touchstone format which has file extensions such as .s1p, .s2p, .s3p, .s4p, etc. You can plot the chart on the Rectangular coordinate or Smith chart.

Use the S-View app to read s-parameters for the commercial RF/Microwave components or systems such as antenna, filters, and amplifiers. Or design your own system, measure data using the network analyzer, and verify the result using S-View.

Launch the app then open files. Or just click the associated file on file explorer.

• Notice
  We will not support updates for S-View Blue anymore. Instead, we recommend you use S-View Red.
  S-View Red uses the new Windows App SDK APIs. And it’s also free.
