rdfs:comment
Normalfrekvenco estas tre preciza frekvenco kiu estas derivata de frekvenca normalo. Je mallongaj bendoj "glataj" frekvencoj estas uzitaj: 2.500 kHz, 5.000 kHz, 10.000 kHz, 15.000 kHz. Sur tiuj frekvencoj ofte estas dissenditaj precizaj tempoindikoj. Normala radiostacioj ankaŭ estas uzataj por dissendi normalfrekvencojn. A frequency standard is a stable oscillator used for frequency calibration or reference. A frequency standard generates a fundamental frequency with a high degree of accuracy and precision. Harmonics of this fundamental frequency are used to provide reference points. Since time is the reciprocal of frequency, it is relatively easy to derive a time standard from a frequency standard. A standard clock comprises a frequency standard, a device to count off the cycles of the oscillation emitted by the frequency standard, and a means of displaying or outputting the result. Eine Normalfrequenz (oder Eichfrequenz) ist eine von einem Frequenznormal hergeleitete hochgenaue Frequenz. Станда́рт частоты́ — высокостабильный по частоте источник электромагнитных сигналов (радиодиапазона или оптических). Стандарты частоты используются в качестве вторичных или рабочих эталонов в метрологических измерениях, а также при производстве высокоточных средств измерений частоты и времени, в радионавигации, радиоастрономии и в других сферах.

Eine Normalfrequenz (oder Eichfrequenz) ist eine von einem Frequenznormal hergeleitete hochgenaue Frequenz. Normalfrekvenco estas tre preciza frekvenco kiu estas derivata de frekvenca normalo. Je mallongaj bendoj "glataj" frekvencoj estas uzitaj: 2.500 kHz, 5.000 kHz, 10.000 kHz, 15.000 kHz. Sur tiuj frekvencoj ofte estas dissenditaj precizaj tempoindikoj. Normala radiostacioj ankaŭ estas uzataj por dissendi normalfrekvencojn. Станда́рт частоты́ — высокостабильный по частоте источник электромагнитных сигналов (радиодиапазона или оптических). Стандарты частоты используются в качестве вторичных или рабочих эталонов в метрологических измерениях, а также при производстве высокоточных средств измерений частоты и времени, в радионавигации, радиоастрономии и в других сферах. A frequency standard is a stable oscillator used for frequency calibration or reference. A frequency standard generates a fundamental frequency with a high degree of accuracy and precision. Harmonics of this fundamental frequency are used to provide reference points. Since time is the reciprocal of frequency, it is relatively easy to derive a time standard from a frequency standard. A standard clock comprises a frequency standard, a device to count off the cycles of the oscillation emitted by the frequency standard, and a means of displaying or outputting the result. Frequency standards in a network or facility are sometimes administratively designated as primary or secondary. The terms primary and secondary, as used in this context, should not be confused with the respective technical meanings of these words in the discipline of and frequency.
