Definition: | fractional change in output frequency resulting from an incremental change in supply voltage, other parameters remaining unchanged Note 1 to entry: In the case of oven controlled crystal oscillators (OCXOs), a considerable time may elapse before the full effect of a supply voltage change is observed, as the temperature of the oven may drift gradually to a new value following the voltage perturbation. Note 2 to entry: This entry was numbered 561-04-14 in IEC 60050-561:1991.
