## Command Syntax

    :FUNCtionN:PARameters:DFEQualizer:TAPS:ULIMit "tap_limit_value, tap_limit_value, …"

The command argument is a string of comma separated list of real numbers (individual tap limit values).

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:TAPS:ULIMit?

## Description

Specifies the upper limit for the tap values for the Decision Feedback Equalizer operator (DFE). Existing tap values are adjusted to be within the limit. Changing an existing tap value beyond the upper limit will increase the upper limit.

Use the `:FUNCtion:PARameters:DFEQualizer:TLUNits` command to specify whether the limit values are unitless or are voltage values.
