# :FUNCtion:PARameters:INTerpolate:METHod

Interpolation Parameters Commands

- :FUNCtion:PARameters:INTerpolate:FACTor
- :FUNCtion:PARameters:INTerpolate:METHod

## Command Syntax

    :FUNCtionN:PARameters:INTerpolate:METHod {SINC | LINear}

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:INTerpolate:METHod?

## Description

Selects a linear or sin(x)/x interpolation for an Interpolation operator (`:FUNCtion:FOPerator`). The number of points in the output waveform is determined by the interpolation factor, which is set using the `:FUNCtion:PARameters:INTerpolate:FACTor` command.

SINC
  Selects the sin(x)/x method, which is the default and is preferred when reconstructing a signal (having evenly spaced samples) that has been bandlimited. The new points are evenly spaced between the original points.
LINear
  Selects the linear method.
