SIGNAL GENERATOR APPARATUS AND METHOD OF CALIBRATION THEREFOR

摘要

A signal generator apparatus (100) comprises a controller (102) coupled to an oscillator circuit (122). The oscillator circuit (122) has a range of output frequencies, the oscillator circuit (122) being arranged to serve at least part of the range of output frequencies by providing a first sub-range of output frequencies and a second sub-range of output frequencies. The first and second sub-ranges overlap to provide a crossover frequency. The controller (102) is coupled to the oscillator circuit (122) and arranged to scan, when in use, at least part of the range of output frequencies and calculate the crossover frequency.
