psd

property ToneToNoiseRatio.psd: Field

Input power spectral density (PSD) as a DPF field.

The PSD field has the following characteristics:

• num_entities = 1

• location = “TimeFreq_sets”

• data: Vector of amplitude values in unit^2/Hz

• time_freq_support: Vector of regularly spaced frequencies in Hz associated with

  amplitude values (from 0 Hz to the maximum frequency)

• unit = “<unit>^2/Hz” (where <unit> is Pa for example).

You can use the ansys.dpf.core.fields_factory.create_scalar_field() function to create the field.
