Audio Interface

Input device (CH1 = L, CH2 = R) Output device Sample rate (Hz)

Sweep Parameters

f₀ (Hz)

f₁ (Hz)

Points/decade

Amplitude (0–1)

Rs (Ω) Ch2 timing correction (samples)

Corrects inter-channel ADC skew. 0 = off. Use +1 for UCA222 (Ch2 leads by 1 sample).

Settle cycles (per point) Measure cycles (per point) Min. measure samples Min. settle samples

Cycles or min-samples, whichever is larger. Keeps high-frequency SNR consistent.
