Studio applies a single smoothing pass to voltammetry traces, a Savitzky-Golay filter, in software rather than on the instrument. The device always streams the raw signal, so the unprocessed trace is preserved alongside the filtered one and you can switch between them at any time.
How it works
A Savitzky-Golay filter slides a small window across the trace and replaces each centre point with the value of a polynomial fitted to the surrounding points. The result keeps the shape and width of real peaks while attenuating short-wavelength noise. It stays much closer to the underlying signal than a plain moving average, which would round off the peak.
Default for new recordings
The Enable filter checkbox at the bottom of the Parameters panel for voltammetry techniques (CV, DPV, SWV) sets which version is shown by default for new recordings. It is on by default; most users prefer a clean trace.
There are no knobs to adjust. The filter is either applied to the displayed trace or it isn't.
Toggle per experiment
Because Studio keeps both versions of every recording, you can flip a single experiment between filtered and unfiltered after the run is finished. Right-click the experiment in the right sidebar and pick Show unfiltered (or Show filtered). The trace, the saved file, and any subsequent export use the selected version.
This means leaving the filter on by default is safe. If you later need the raw signal for publication, noise diagnostics, or comparison against another instrument, switching is one right-click rather than re-running the experiment.
Compatibility
The checkbox appears in the parameter panels for Cyclic Voltammetry, Differential Pulse Voltammetry, and Square Wave Voltammetry. It does not apply to EIS, chronoamperometry, chronopotentiometry, or potentiometry. Those techniques have their own noise-handling characteristics that smoothing would interfere with.
