For example, a rubidium oscillator of high quality might change its frequency due to aging at a rate of less than 1 × 10-11 per month. [11] However, if an inexpensive quartz oscillator is used, it might age 1000 times faster than a rubidium oscillator, so aging compensation will be needed more often and the aging rate will be less predictable.
