Claim 6:
7. A method, comprising:
generating an amplifier RF input signal to drive an amplifier circuit, the amplifier circuit configured to cause a RF signal to be applied to a multipole mass analyzer;
determining, by a controller circuit, that an actual amplitude of the RF signal is different than an expected amplitude of the RF signal;
identifying, by the controller circuit, one or both of: (i) current environmental characteristics and past environmental characteristics of the multipole mass analyzer, or (ii) current performance characteristics and past performance characteristics of the multipole mass analyzer, the past environmental and performance characteristics stored in a memory; and
adjusting, by the controller circuit, the amplifier RF input signal in view of one or both of: (i) a comparison of the current and past environmental characteristics of the multipole mass analyzer, or (ii) a comparison of the current and past performance characteristics of the multipole mass analyzer.
