Plot and export S-Parameter traces from Studio

Before starting

Use InductEx® 8 with a matching Studio/Core runtime and a complete writable calculation. The current-source Windows sampled-response route has scoped native checks; the final distributed package and physical export dialogs remain pending.

Steps

1. Open the S-Parameters response associated with the intended successful run, or deliberately open the intended response JSON.
2. Read whether the response is a rational model or sampled data. Select the traces and visible frequency band needed for the comparison.
3. Use Export PNG for the visible chart and legend, or Export CSV for the selected traces over the visible band.
4. Record the response source, frequency band and selected traces beside the exported file.

Check the result

CSV columns are trace,f_Hz,re,im,valid. Frequency is in Hz and the real/imaginary parts are exported directly.

Sampled responses use solved points and complex interpolation. Zooming or increasing plot density cannot recover an unsolved narrow feature. Adaptive traces may have different frequency grids.

Keep display and numerical data separate

The native CSV writer preserved the current Core complex values in four- and thirteen-point S11 results and the corrected 2:1/S21 selection. Selecting linear magnitude instead of dB left CSV bytes unchanged. PNG exports produced valid native chart images.

A zoomed sampled export can include interpolated boundary coordinates. In the checked view, eleven interior points plus two interpolated boundaries still produced thirteen rows; Reset restored the original CSV bytes. The underlying Core result stayed unchanged. Read the solved-data provenance rather than inferring new solves from row count.

For a complete worked frequency-grid example, use the related refinement guide. Direct native writer calls do not establish physical Save, invalid-destination retry or Cancel behaviour.

If the problem remains

If no appropriate response is loaded, check successful-run association and open the intended JSON explicitly. Do not use an old or ambiguous model as a new extraction result.

An Invalid trace S99 diagnostic on a two-port response is corrected by selecting S11, S21 or 2:1 and Apply traces. The checked correction exported S21; the previous curve can remain visible while the selector is invalid.
