frequency, the nameplate frequency is labeled on the oscillator’s output. For example, a DUT with an output labeled "5 MHz" is supposed to produce a 5 MHz frequency. The calibration measures the difference between the actual frequency and the nameplate frequency. This difference is called the frequency offset. There is a high probability that

Since the frequency of the counter is the frequency of th e oscillator divided by 32 (only the 8 MSbits are saved on the 13 bits of the counter), if the oscillator is at 1 MHz, the result of the count between two edges (which have a 10 ms interval), is 138h for the European standard
Frequency Calibration Using WWV - N5DUX
http://n5dux.com/ham/files/pdf/Frequency%20Calibration%20Using%20WWV.pdf
The calibration technique Rather than calibrate the oscillator against the WWV carrier frequency, the technique outlined here uses the audible ticks that are transmitted by WWV and WWVH to identify the seconds. Each tick transmitted by those services consists of a 1000-Hz, 5-ms tone. The actual tick, therefore is composed of five cycles of a

Note: For example, if the nominal HSI frequency is 16 MHz, the defined calibration period, Tcal, is 20 ms (if the mains has a frequency of 50 Hz), and the known number of calibration signal periods, L, is 8 then the ideal value captured by the timer is 2 560 000 (0x271000) The calibration algorithm is described in Figure 3.

Comment on the accuracy of the calibration on the audio frequency oscillator. Practical advice. Settings on all devices can drift. You could always check some settings of the time base against mains frequency. If possible it is a good idea to switch on devices some time before they are needed so that they warm up to a steady temperature.

calibration of the oscillator can be reset against a frequency standard. Such controls usually consist of re sistance verniers located in the fre quency-determining network. If the oscillator calibration is corrected from time to time with these con trols, accuracies within 1% can be easily maintained. At frequencies above a few kilo

Whether you use an existing piece of gear or adapt a TCXO the next hurdle is calibration. You can usually get within 50Hz or so by zero beating against WWV by ear but a better method is needed. The simple one chip TRF 10MHz WWV receiver described below makes calibration to.1 to .01 PPM (10-7 or 10-8) quick, easy and reliable. I listened at ...
