What OCXO 10Mhz Frequency Reference Are Comprised Of

By Gwen Lowe


In here, the crystal and the circuitry responsible for temperature sensitivity have to be kept in a controlled structure. This ensures that it is in a stable condition of temperature, which should be higher than that ambient temperature necessary for exposing OCXO 10MHz Frequency Reference. In fact, it is better if the oven is set to turnover temperature of the resonators so that it balances with the external temperature.

Controlling the temperature will enable anomalies which are attached to temperature effects be minimized as much as possible. The anomalies can prove destructive to the resonators and may even allow compensation to a limited allowance. It could be possible to engage top overtone crystals to be used in control of temperatures. Being in controlled conditions make them better.

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.

Stability comes about as a result of the dynamic characteristics as well as the static. Oven accuracy, range of design temperature, the resonator and other components determine the stability. Such temperature stability performs within the recommended range. The narrow ones have proved to have increased stability due to the fact that restriction is possible to a specific area.

The oven controlled oscillator needs more power in terms of consumption because it takes a long time to warm up. It is the kind of insulation used that majorly determines the power needed to be used for oven heating. If it is high, the heat usage will be reduced and this results in usage of less power.

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.

Proper regulation should also be carried out so that the voltage supply does not have any variations. If not checked, then disturbances may be noticed within oscillator frequency and this could hinder its performance. Difference in power if realized can cause delay and let the supply go back to equilibrium, leading to wastage of more time.

Since the oscillator is sensitive to load, an amplifier could be used so that multiple outputs can be obtained. This is the reason why they should be built around the oven so that temperature stability does not interfere so much. Humidity also needs to be checked because it could have some impact on 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.
