Touchstone, CSV, and images

RayRF exports from two tabs: S-Parameters and Radiation Pattern. The S-Parameters tab writes Touchstone, CSV, and PNG. The Radiation Pattern tab writes CSV of the polar cuts. Editor view export and PNG-sequence export of the 3D radiation lobe are on the roadmap. Those buttons do not exist in the app yet.

Touchstone (.sNp)

S-Parameters tab, then Export Touchstone. The standard interchange format for circuit simulators (ADS, AWR, QUCS, ngspice with extensions). RayRF writes a header line with the frequency unit (default GHz), the data format (default RI for real and imaginary), and the reference impedance (defaults to the project's port Z0, usually 50 ohms). The file extension follows the port count: .s1p for a single port, .s2p for two ports, and so on.

Touchstone export requires a Pro plan
Hobby plans can view S-parameters and export them as CSV or PNG. Touchstone export is a Pro feature. Upgrade from the account dashboard if you need it.

CSV

S-Parameters tab, then Export CSV. The dialog offers three layouts:

  • Only dB magnitude. One column per parameter, dB only. Smallest file, fine for a quick report.
  • Both data sets in two CSVs. One file with dB and phase, a second file with real and imaginary parts.
  • Both combined in one CSV. Every column in a single file.

The Radiation Pattern tab also has an Export CSV button. It saves the displayed polar cuts (E-plane and H-plane) as a single CSV.

PNG (S-parameter plots)

S-Parameters tab, then Export PNG. With Split View active the dialog asks whether you want only the dB plot, two separate PNGs (one per panel), or one wide combined image. The export captures the current view at the current zoom and camera, so line up the view first.

Save confirmation

Each successful export drops a small toast in the corner of the window with the saved file path.
