It is extremely important to keep both the crystal and circuitry in a controlled structure so as to manage temperature sensitivity. This is what denotes a stable temperature, which ought to be higher than the one responsible for exposing OCXO 10MHz Frequency Reference. Better still; the oven can perform better if it is set to turnover resonators degree to give it the capability of balancing with the outside temperature.
If the temperature is controlled, then anomalies associated with temperature effects will be reduced to minimal. These temperature anomalies have effects on the resonators and may just allow compensation within a limited allowance. Higher overtone crystals may also be used in such controlled temperatures. This is better because they are stable in controlled conditions.
Stability is highly enabled with these oscillators as compared to the others like TCXO and SPXO which have no temperature control mechanisms. Rather, their temperature characteristics are determined by the crystal units. The oven controlled oscillator is better placed because of its oven block which is capable of maintaining a stable temperature as required.
Its stability is majorly resulting from both the static and dynamic characteristics. These could be on the resonator, the range of the design temperature and stability of other components such as the oven accuracy. Even though temperature stability works in a given range, narrow ranges give improved stability because lots of it is restricted and channelled to a specific section.
More power needs to be considered for the oven controlled oscillator because its consumption is enormous. Depending on the insulation kind, you will be able to determine the power needed for such operations. The higher it goes, the lesser heat used, which in turn helps in usage as minimal as possible.
The oven temperature is set first and be put at higher degrees than the normal ambient temperature, to enable proper control by the oven. The resonator should then be warmed up before being turned on. This is to allow the oven to balance to equilibrium.
Regulation is also necessary to avoid variations of voltage supply. If this happens, then disturbances are likely to be created within the oscillator frequency. This results from the difference in the power and may end up taking quite a long time to go back to equilibrium.
The oscillator is quite sensitive to load and so you need to engage the functions of an amplifier to give multiple outputs. If built around the oven, then stability of the temperature will not interfere with it. It is better to check out on humidity so that you guard the stability.
Such issues may be averted by measuring instability and modelling it to the required standards. Control mechanisms are also available and can be used for the better to avert instability. Temperature compensation can be achieved through such mechanisms. Additional characteristic like retrace is another option which can be applied for these aversion purposes.
