PRS10 铷钟

PRS10铷原子振荡器是美国 SRS 公司生产的高性能铷原子振荡器产品,具有低相噪、低漂移、稳定度高等特点。可广泛应用于电信、时统、雷达、计量标准等领域。 PRS10是一款超低相位噪声的10MHz铷原子振荡器件。极低的月老化率(<5E-11),使其非常适合作为一款时基部件用于精密的频率测量。该振荡器有一个1pps输入端口可用于外部参考标准(如GPS)进行锁相并具有72小时Strautm 1 Level的保持能力。铷灯的使用寿命预期可达20年且该器件被有一个标准RS-232计算机接口。


超低相位噪声(<-130 dBc/Hz at 10 Hz)

1pps输入用于时间标记或者相位锁定

72小时Strautm 1 Level的保持能力

可利用RS232接口进行测试,控制及校准

寿命可达二十年
