摘要
在空间恶劣环境下要求星载高稳晶振正常有效地工作,需要对其在空间辐照环境下的频率特性变化进行研究,利用地面辐照设备模拟空间辐照环境,通过不断增加辐照剂量,研究晶振相位噪声、短期频率稳定度、谐杂波以及输出功率等特性。
In order to insure the high stability crystal on satellite to work normally, the change of frequency character needs to be researched under space radiation environment, using ground radiation de- vice to simulate space radiation environment, and phase noise, short term frequency stability, harmonics, spurious and output power also need to be researched.
