The actual value of the frequency difference between the nominal value of the frequency, usually with relative values \u200b\u200bsee formula (1).
y = fx-f0f0
(1)
Where.
y --- frequency deviation;
f0 --- nominal frequency value;
fx --- frequency found.
3.3
Frequency accuracy frequencyaccuracy
The maximum range of frequency deviation. Indicates how close to the nominal value of frequency actual value expressed in numerical quantitation without sign.
