Abstract
A process for frequency tuning microwave bridges and a device for practicing such a process. The process is characterized in that it consists in subjecting a resonator (3) to the radiation delivered by a secondary microwave source (10) sweeping a wide band of frequencies comprising particularly the frequency (F) of radiation delivered by the principal microwave source (1). The radiation reflected by the resonator (3) is displayed and the relative positions are marked along the frequency spectrum, of the frequency (F) and of the frequency of resonance (Fr) of the resonator (3). The frequency (F) of radiation delivered by the principal microwave source (1) is varied while controlling in real time the effect of this variation on the relative positions of the frequencies (F and Fr).
