Nominal frequency - oscillator frequency, which must lie in fixed range and which can be randomly changed in this range.
Supply current at switch on - in case of OCXO oscillators on switch on after ca 2 to 10 minutes according to the oscillator type it is necessary to warm up the thermostat on operating temperature. The oscillator takes higher supply current during this time.
Frequency stability with temperature - set the maximal frequency changes in fixed temperature range. It will be set in ppm, also in millionth of nominal frequency of oscillator.
Frequency stability with supply
voltage - set how can be the nominal frequency changed in case of supply
voltage change in the range fixed at supply voltage. It will be set in ppm.
Pulling voltage - it is possible to fine-tune the nominal frequency of oscillator with connection of voltage to one its outlet (marked V ctrl) at most of oscillators. At some oscillator it is possible to use steady voltage of the lead which is marked Out Uref for pulling voltage setting.
Mechanical frequency adjustment - it is possible to fine-tune with tuner the oscillator nominal frequency at some of oscillators.
Minimal frequency adjustment - means minimal change of nominal frequency which can be reached in the whole pulling voltage range or through mechanical adjustment.
Warm-up time - in case of OCXO oscillators. Time necessary for oscillator warming up to operating temperature.
Frequency offset - stated on the oscillator plate sets the
operating frequency shift from nominal frequency at the temperature of 25°C.
The frequency symmetrical offset in fixed temperature range to nominal frequency
is secured with that.
