PRS10銣原子振蕩器是美國 SRS 公司生產(chǎn)的高性能銣原子振蕩器產(chǎn)品，具有低相噪、低漂移、穩(wěn)定度高等特點(diǎn)。可廣泛應(yīng)用于電信、時(shí)統(tǒng)、雷達(dá)、計(jì)量標(biāo)準(zhǔn)等領(lǐng)域。 PRS10是一款超低相位噪聲的10MHz銣原子振蕩器件。極低的月老化率（＜5E-11),使其非常適合作為一款時(shí)基部件用于精密的頻率測(cè)量。該振蕩器有一個(gè)1pps輸入端口可用于外部參考標(biāo)準(zhǔn)（如GPS）進(jìn)行鎖相并具有72小時(shí)Strautm 1 Level的保持能力。銣燈的使用壽命預(yù)期可達(dá)20年且該器件被有一個(gè)標(biāo)準(zhǔn)RS-232計(jì)算機(jī)接口。

特點(diǎn)：

超低相位噪聲（<-130 dBc/Hz at 10 Hz）

1pps輸入用于時(shí)間標(biāo)記或者相位鎖定

72小時(shí)Strautm 1 Level的保持能力

可利用RS232接口進(jìn)行測(cè)試,控制及校準(zhǔn)

壽命可達(dá)二十年
