ʻO ka Oscillator Crystal Controlled Oven (OCXO)

ʻO ka Oven Controlled Crystal Oscillator (OCXO) he oscillator aniani e hoʻohana ana i ka pahu wela mau e mālama i ka mahana o ka quartz crystal resonator i loko o ka oscillator kristal mau, a ua hoʻemi ʻia ka hoʻololi alapine o ka oscillator i hoʻololi ʻia e ka hoʻololi ʻana o ka mahana ambient. Hoʻokumu ʻia ʻo OCXO me kahi kaapuni hoʻomalu pahu wela mau a me kahi kaapuni oscillator, maʻamau e hoʻohana ana i kahi "alahaka" thermistor i haku ʻia me ka amplifier series differential e hoʻokō i ka mana wela.

Loaʻa iā ia nā ʻano penei:

1. Ka hana pānaʻi wela ikaika: Loaʻa ʻo OCXO i ka uku wela i ka oscillator ma o ka hoʻohana ʻana i nā mea ʻike wela a me nā kaapuni hoʻopaʻa. Hiki iā ia ke mālama i kahi puka alapine paʻa i nā wela like ʻole.
2. Kiʻekiʻe alapine paʻa: OCXO maʻamau i pololei loa alapine paʻa, kona alapine deviation liʻiliʻi a me ka paʻa. Hana kēia i ka OCXO kūpaʻa kiʻekiʻe i kūpono no nā noi me nā koi alapine kiʻekiʻe.
3. Ka manawa hoʻomaka wikiwiki: He pōkole ka manawa hoʻomaka o OCXO, maʻamau he mau milliseconds wale nō, hiki ke hoʻopaʻa koke i ka alapine puka.
4. ʻO ka mana haʻahaʻa haʻahaʻa: ʻO ka OCXO ka mea maʻamau e hoʻopau i ka mana liʻiliʻi a kūpono i nā noi me nā koi ikaika o ka mana, hiki ke mālama i ka ikehu pākaukau.

Nā noi o nā Oscillator Crystal i mālama ʻia i ka umu:

1. Pūnaehana kamaʻilio: Hoʻohana nui ʻia ʻo OCXO i ke kamaʻilio kelepona, ka leka uila, ka hoʻouna ʻana i ka ʻikepili uila a me nā kahua ʻē aʻe e hāʻawi i kahi alapine kuhikuhi paʻa.
2. Hoʻonohonoho a me nā ʻōnaehana hoʻokele: Ma nā noi e like me GPS a me Beidou navigation System, hoʻohana ʻia ʻo OCXO e hāʻawi i nā hōʻailona uaki pololei, e hiki ai i ka ʻōnaehana ke helu pololei i ke kūlana a me ke ana ʻana i ka manawa.
3. Mea hoʻohana: Ma ke ana pololei ʻana i nā mea hana a me nā mea hana, hoʻohana ʻia ʻo OCXO e hāʻawi i nā hōʻailona uaki pololei e hōʻoia i ka pololei a me ka reproducibility o nā hopena ana.
4. Mea uila uila: Hoʻohana nui ʻia ʻo OCXO i ke kaapuni uaki o nā lako uila e hāʻawi i kahi alapine uʻi paʻa e hiki ai i ka hana maʻamau o ka hāmeʻa.

I ka pōkole, loaʻa iā OCXO nā hiʻohiʻona o ka hana pānaʻi wela ikaika, ke kūpaʻa kiʻekiʻe o ke alapine, ka manawa hoʻomaka wikiwiki a me ka hoʻohana haʻahaʻa haʻahaʻa, kūpono ia no nā noi me nā koi alapine kiʻekiʻe a me ka maʻalahi i ka hoʻololi ʻana o ke kaiapuni.

Kaʻaleʻaleʻahoʻolako i ka walaʻau haʻahaʻa OCXO.
