A frequency band is a frequency range with a denomination.
Statements concerning step width and dwell time can optionally be specified ( see also DIN 40 839-4).
The DUT can be tested in different frequency ranges with corresponding requirements. The frequency bands can be specified including the relative or the absolute step width Df and the dwell time during the test (as given in the definition Representation example for frequency bands (I)).
