<SignalCalibrationIdentifier> is a container object for the calibration parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to IGasChromatographCalibrationType to add Gaschromatograph signal specific calibration variables. Since it is a placeholder, an instance of GasChromatographSignalType can have several calibration objects.

SignalConditionSet is a container object for the condition parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to IGasChromatographSignalConditionSetType to add Gaschromatograph signal specific condition variables.

The components of GasChromatographSignalType have additional references which are defined inTable 201.
