## Command Syntax

    :FUNCtionN:SNDRatio:RNComp {OFF | AUTomatic | CUSTom}

Where N identifies one of sixty four {1:64} math functions that you can create. For example, `:FUNCtion2`.

## Query Syntax

    :FUNCtionN:SNDRatio:RNComp?

## Description

This command disable disables RN compensation (`OFF`), enables compensation for oscilloscope RN (`AUTomatic`), or enables user-defined values for RN compensation (`CUSTom`).

If there are known contributors to random noise, you can use RN Compensation to compensate or remove noise from the measurement results.

When `CUSTom` is selected, use the `:FUNCtion:SNDRatio:RNCValue:LEVel` command to specify the appropriate RN compensation values for the symbol levels.
