PRS10 GPS铷钟 铷钟振荡器
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(-130dbc/hz@10hz)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
