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
