Abstract

We present a reconfigurable microwave frequency measurement technique with adjustable measurement range and resolution. The key novelty of the technique is the employment of stimulated Brillouin scattering, which results in a tunable amplitude comparison function, leading to an adjustable measurement range and resolution. The proposed technique is switchable between a wideband tunable narrow measurement range (2GHz) with high resolution (±0.05GHz) and a fixed wide measurement range (12 GHz) with moderate resolution (±0.25GHz).
