An offset added to all power levels read by the OCM,
to compensate for any monitor port losses.
Generally offset values depends upon board type connected.
Based on the connected board type, OCM2P sets following default
values, while OCM8P sets 20dB as default value. In all other cases
the user is expected to set the offset manually or choose an option
to read the offset from amplifier, if connected.
