source_bbn

property SourceBroadbandNoise.source_bbn: FieldsContainer

Source data of the broadband noise source.

The broadband noise source data consists of a series of spectra, each corresponding to a control parameter value.

Each field contains the level over frequency of the noise at a given value of the control parameter. Level over frequency may be specified as a power spectral density (PSD) in Pa^2/Hz, as octave-band levels in Pa^2, or as 1/3-octave-band levels in Pa^2. The unit must be indicated in each field’s unit. The type of data (‘Narrow band’, ‘Octave’, or ‘Third octave’) must be indicated in the field’s FieldDefinition attribute, as a quantity type.

The control parameter values corresponding to each spectrum must be stored in the fields container’s support named “control_parameter_1”.
