What is Warm-up time of an OCXO? OCXO恒温晶振的预热时间是多少？

Oven Controlled Crystal Oscillators, are known to provide a stable frequency oscillation across a wide range of operating temperatures. They do this by heating the oven in which the crystal oscillators are placed, so that temperature variations in the environment outside the oven have less of an effect on the oscillation frequency.

恒温槽控制的晶体振荡器，是已知的提供一个稳定的频率振荡在很宽的工作温度范围内。他们通过加热放置晶体振荡器的“恒温箱”来实现这一点，因此恒温箱外环境的温度变化对振荡频率的影响较小。

The time-period taken by an oven to warm up and reach its ideal operating temperature is known as Warm-up Time. An OCXO is considered to provide a stable oscillation frequency after the warm-up time.

恒温槽预热并达到理想工作温度所需的时间称为预热时间。OCXO恒温晶振被认为是在预热时间之后才开始提供稳定的振荡频率。

Warm-up time depends on the following main factors恒温晶振预热时间主要取决于以下四个因素：

• Power available可用功率
• Size of the oven烤箱的大小
• Insulation quality保温质量
• Ambient temperature环境温度

Typical warm-up times are from 1 minute to 15 minutes. This is usually specified in the datasheet of an OCXO. The shorter the warm-up time the quicker that OCXO will reach the point of stable operation.

恒温晶振典型的热身时间从1分钟到15分钟。该时间通常在恒温晶振的数据手册中有具体指定。预热时间越短，恒温晶振达到稳定运行点的速度越快。
