III. Deep Dive into Key Performance Danfara minnu bɛ u ni ɲɔgɔn cɛ
1. Tiɲɛni & sabatili: Danfara jɔnjɔn
OCXO yebɛ tɛmɛn waati kunkurunnin- sabatili kan. SC-kristali tigɛlenw sanfɛ-da bɛ se ka 5×10−13 sɔrɔ segin 1 kɔnɔ, hali ka tɛmɛ rubidiyɔmu atomi wagati dɔw kan minnu ka dɔgɔn-. Nka, k’a sababu kɛ kɔrɔya ko kɛlenw ye minnu bɛ sɔrɔ kuran kristalɛw kɔnɔ, u sabatili kuntaalajan- bɛ dɔgɔya dɔɔnin dɔɔnin, wa u ka fɔcogo tiɲɛni bɛ wuli waati kɔnɔ.
Atomikɛ wagatiwnafa ka bon kosɛbɛ waatijan-tiɲɛni ni sabatili la. Atomiki jiginni fɔcogo ye fɛnɲɛnamaw ka fɛn basigilenw ye, minnu tɛ nɔ bila kɛnɛmafɛnw na i n’a fɔ funteni, degun walima yɛrɛyɛrɛ. Seziyɔmu atomikɛlanw bɛ sabatili sɔrɔ waatijan kɔnɔ min ye 1×10−13/tile ye ani ka diɲɛ atomikɛ waati (TAI) ɲɛfɔ. Idɔrɔzɛni masɛriw ka fisa ni waati kunkurunnin- sabatili ye, u bɛ se ka 1×10−14 sɔrɔ segin 1 kɔnɔ (Allan deviation), min ka ɲi kosɛbɛ baarakɛcogo la minnu bɛ teliyaba ɲini yɔrɔnin kelen na kosɛbɛ.
2. Fasa mankan: OCXO ka Nafa dafalen
Fasa mankan ye waati kunkurunnin dɔ ka fɔcogo sabatili jiralan kɔrɔlen ye, min bɛ nɔ bila taamasiyɛn-ni-mankan hakɛ la k’a ɲɛsin ɲɔgɔn ma kumaɲɔgɔnya siratigɛw la ani dɔnni tiɲɛni rada siratigɛ la.
OCXO ye, ka baara kɛ ni kuran kristalɛ ka Q-factor (106~107) ye min ka bon kosɛbɛ, o bɛ tɛmɛ atomikɛlan wagati bɛɛ kan kosɛbɛ fasa mankan surun- la (1Hz~1kHz offset). OCXO 10MHz danma bɛ se -165 dBc/Hz lamini na 1kHz offset la, k’a sɔrɔ rubidium wagatiw bɛ se -145 dBc/Hz ɲɔgɔn ma cogoya la. O b’a to OCXO bɛ kɛ sigida sɛgɛsɛgɛlikɛlan ye min ka fisa ni rada, ɛntɛrinɛti kɛlɛ, ani sɛgɛsɛgɛli & sumanikɛlan kɔrɔlenw ye.
Atomikɛ wagatiw have an advantage in far-out phase noise (>100kHz offset) bawo u tɛ ni masin-rezɔn-yɔrɔw ye minnu bɛ Sɔrɔ kristalɛ-yɛrɛyɛrɛw la.
3. Holdover Capability: Atomike wagatiw nafa jɔnjɔn

OCXO yebɛ ni free-run frequency drift nafama ye, ni sanga 24-li filiw bɛ se mikrosekɔndi kɛmɛ caman ma ani tile 7 filiw bɛ se ka tɛmɛ milisekɔndi 10 kan, o b’a to a tɛ bɛn baara yɛrɛmahɔrɔnyalen kuntaalajan ma.
Rubidium Atomikɛ wagatiwbɛ quantum leap di holdover baarakɛcogo la, ni sanga 24 filiw ye minnu bɛ kɛ mikrosekɔndi damadɔ dɔrɔn na ani tile 30 filiw minnu bɛ kɛ mikrosekɔndi 500 jukɔrɔ, minnu bɛ se ka holdover yɛrɛmahɔrɔnyalen kɛ dɔgɔkun caman walima kalo caman yɛrɛ kɔnɔ.Seziyɔmu ni idɔrɔzi wagatiwka holdover kabakoma sɔrɔ, ka tiɲɛni mara san caman kɔnɔ ni filiw ye milisekɔndi 1 jukɔrɔ.
