What Happens Behind OCXO 10Mhz Frequency Reference

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.

Anomalies related to temperature effects can be minimized if the temperature can be controlled to the required level. Such anomalies can affect the resonators and cause limited allowance and compensation. In the controlled temperature, overtone crystals work better and may also be used. The reason for better performance is that they are stable when the conditions are controlled appropriately.

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.

It is the dynamic and static characteristics that bring about stability. Things like the accuracy of the oven, the resonator and even some other components are responsible for the kind of stability you can get. It is at a certain recommended range that this temperature stability can perform within. The narrow ranges are better placed as it allows restriction to the needed 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.

If you want to minimize variations, then you have to carry out regulations. This is important so as to help reduce disturbances within the oscillator frequency. It is the difference in power that causes this to happen. If not dealt with, then it may go back to equilibrium.

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.

Measuring instability is possible in order to avert the well known issues that arise from temperature variations. Control mechanisms can be widely used for aversion of instability to help achieve reasonable standards. They work through temperature compensation so as to improve the stability statue. Inclusion of retrace as an additional characteristic series could be very helpful for standard purposes.
