Claim 16:
17. A method of tuning an inertial sensor comprising the steps of;
driving a resonator assembly comprising at least one resonator by applying a drive signal to drive means coupled to the reasonator assembly;
sensing a first amplitude of oscillation of a resonator of the resonator assembly at a first frequency and a second amplitude of oscillation of a resonator of the resonator assembly at a second frequency;
driving a resonator assembly with an initial pumping signal having a frequency substantially equal to the difference between the first frequency and the second frequency,
determining a ratio of the first amplitude of oscillation and the second amplitude of oscillation when the resonator assembly is being driven by the initial pumping signal, and
iteratively adjusting the amplitude and/or the frequency of the initial pumping signal until the ratio is equal to a predetermined value.
