## Command Syntax

    :FUNCtion{1:64}:PARameters:FFT:DETector:TYPE {OFF | SAMPle | PPEak | NPEak | NORMal | AVERage}

Where N identifies one of up to 64 possible operators {1:64} that can be defined as part of a math function. The operators are numbered in the order that they were originally added to the function.

## Query Syntax

    :FUNCtionN:PARameters:FFT:DETector:TYPE?

## Description

Detectors decimate the number of points on screen to at most the number of detector points (or buckets — see `:FUNCtion:PARameters:FFT:DETector:COUNt`). 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.

- `PPEak` — Takes the most positive point in every bucket.

- `NPEak` — 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.
