## Command Syntax

    :FUNCtionN:PARameters:DFEQualizer:SOUTput {ON | OFF | 1 | 0}

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:DFEQualizer:SOUTput?

## Query Response

    {1 | 0}

## Description

After a Decision Feedback Equalizer operator (DFE) (`:FUNCtion:FOPerator`) is applied, the eye drawn is attenuated. To amplify the eye back to its original size (so you can directly compare the eye at the receiver to the eye at the transmitter) a gain factor needs to be applied. The `:FUNCtion:PARameters:DFEQualizer:SOUTput` (Scale Output) option specifies that a constant be applied to both the unequalized input signal and the corrected decision threshold value. A value of 1 means there is no gain applied to the DFE eye diagram (like multiplying by 1).

OFF
  No gain is applied (gain value of 1).
ON
  Specifies that a calculated gain be applied to both the unequalized input signal and the corrected decision threshold value.
