## Command Syntax

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

Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is `CHANnel4_2`.

## Query Syntax

    :CHANnelN: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 `:CHANnel:SNDRatio:RNCValue:LEVel` command to specify the appropriate RN compensation values for the symbol levels.
