- :CHANnel:ESCaling:ATTenuation
- :CHANnel:ESCaling:DB
- :CHANnel:ESCaling:GAIN
- :CHANnel:ESCaling:OFFSet
- :CHANnel:ESCaling:STATe
- :CHANnel:ESCaling:UNITs

## Command Syntax

    :CHANnelN:ESCaling:DB <dB>

<dB> is a double.

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:ESCaling:DB?

## Description

Enters or queries the external hardware (like a transducer, for example) attenuation/gain/dB setting as a dB value.

You can also specify the external hardware attenuation/gain/dB setting using the `:CHANnel:ESCaling:ATTenuation` or `:CHANnel:ESCaling:GAIN` commands, respectively. These commands give you three ways of interpreting the same setting.

To apply external hardware compensation, use the `:CHANnel:ESCaling:STATe` command.
