WebMay 30, 2024 · Another factor that affects the crystal aging is its drive level. Lowering the drive level can reduce the aging effects. The aging effect an overdriven crystal experiences in one month can be as much as that of a 1-year-old crystal that is driven at the rated power level. Figure 6 shows a typical aging plot. Figure 6.
