Calibration of marginal oscillator sensitivity for use in ICR spectrometry
Abstract
A new design of a Q-spoiler, a constant reference load, is introduced and evaluated. The device is useful in the calibration of a marginal oscillator's relative sensitivity variations with frequency. In a capacitive divider design, the loading of the marginal oscillator with respect to frequency is largely dependent on the choice of components. The new design uses a large resistance and compensates for the resistor's capacitance by switching between the resistor and another leg of the circuit that has a matched capacitance.
