Abstract
Control of an amplitude of a signal applied to a component of a mass spectrometer is described. In one aspect, a mass spectrometer includes a component and a resonant circuit to generate a radio frequency (RF) signal applied to the component. An amplitude control circuit can be inductively coupled with inductors of the resonant circuit to selectively discharge energy from the resonant circuit and, therefore, adjust the amplitude of the signal in particular situations.
