Abstract: This disclosure relates to optical RF spectrum analysers and methods for analysing an input RF signal. An optical modulator modulates an input RF signal onto a carrier frequency and an optical spectral weight with a spectral weight function modifies the modulated optical signal. The spectral weight defines a frequency relationship between the spectral weight function and the carrier frequency. A frequency control module modifies the frequency relationship between the spectral weight function and the carrier frequency over time. An optical sensor senses the modified optical signal over time and to generates an RF signal over time. A signal recovery module calculates the RF spectrum based on the RF signal over time. Shifting the spectral weight against the carrier frequency over time results in a high spectral resolution even if the spectral weight is relatively broad band. The result is an increased spectral resolution at a reduced price/complexity and increased robustness.
