WebOct 2, 2015 · Drive level can be determined through simulation of the oscillator with the maximum expected value of R1 used in the crystal model. If a realistic model of the behaviour of the active section of the oscillator is not available then the current in the crystal should be measured using a high bandwidth current probe. WebDrive Level The drive level is the power dissipated by the crystal unit while operational. The power is a function of the applied current and is usually expressed in terms of milliwatts (mW) or microwatts (µW). Crystal units are specified as having certain maximum values of drive level, which transform as functions of the frequency and
