# FFT Peak Detection

- Enable — When checked (enabled), the first N peaks in the FFT above the specified Peak Level are annotated. N is specified by the Max Peak Count control.

  The annotated peak values are displayed in the FFT Peaks panel.

  The peak level appears as a marker in the FFT window.

- Max Peak Count — Specifies the number of peaks in the FFT to annotate.

- Peak Level — The level above which peaks are identified.

- Peak Sort — Specifies whether peaks are annotated by Decreasing Magnitude, Increasing Frequency, Decreasing Frequency, or Increasing Magnitude order. Peak annotations are numbered according to the chosen sort.
