.s2p files with # GHZ S <MA|DB|RI> R 50.
- Plots
S11, S21, and S22 in dB.
- Opens
.s2p files as the default S2P Preview custom editor.
- Opens in
Auto / Full file range mode and highlights an editable passband.
- Keeps
1-10 GHz as the first configurable preset.
- Adds and deletes passband presets from the preview.

-3 dB, -15 dB, and -20 dB.

S21 and S11/S22.
Unsupported for the current release: Touchstone 2.0/2.1 keyword blocks, Smith chart, multi-file overlays, and PNG export.
Use
Open a .s2p file. VS Code should use the S2P Preview custom editor by default.
To open the preview from an already-open text editor, run:
S2P: Preview Current File
You can also right-click a .s2p file in Explorer and run the same command.
Use the Start GHz and Stop GHz fields in the preview to update the shaded band and metrics interactively.
Use the preset dropdown to activate a preset, save the current range as a new preset, or delete a preset with the x at the end of its row.
To return to the active preset after manual edits, open the dropdown and select that preset again.
To inspect raw Touchstone text, use Reopen Editor With... and choose Text Editor.
Settings
{
"s2pPreview.passbandPresets": [
{ "label": "1-10 GHz", "startGHz": 1, "stopGHz": 10 }
],
"s2pPreview.defaultPassbandPreset": "Auto / Full file range"
}
Preset add/delete actions update user settings by default. If the workspace already defines s2pPreview.passbandPresets or s2pPreview.defaultPassbandPreset, those actions update the workspace settings instead.
