ABSTRACT:
A method for mapping a spectrum obtained from signals under test corresponding to linearly spaced frequencies to logarithmically spaced frequencies in a measuring apparatus. A spectrum within a predetermined frequency range from logarithmically spaced frequencies is selected from this spectrum corresponding to linearly spaced frequencies and vector averaging of the selected spectrum is performed.
