# FFT Detector Points

- Detector Type — Detectors decimate the number of points on screen to at most the number of detector points (buckets). Detectors give you a way of manipulating the acquired data to emphasize different features of the data. The detector types are:

  - Off — No detector is used.

  - Sample — Takes the point nearest to the center of every bucket.

  - Positive Peak — Takes the most positive point in every bucket.

  - Negative Peak — Takes the most negative point in every bucket.

  - Normal — Implements a rosenfell algorithm. For details, see the Spectrum Analysis Basics application note.

  - Average — Takes the average of all points in every bucket.

- Detector Points — Specifies the maximum number of points (buckets) that detectors should decimate to.
