Oscillator Crystal i hoʻomalu ʻia i ka umu
ʻO ka Oscillator Crystal i mālama ʻia i ka umu (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 o ka oscillator output i hoʻololi ʻia e ka hoʻololi ʻana o ka mahana i ka liʻiliʻi. .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 hiʻohiʻona penei:
1.Strong pānaʻi pānaʻi hana: OCXO loaʻa ka wela wela i ka oscillator ma o ka hoʻohana 'ana i ka wela sensing mea a me ka stabilizing kaapuni.Hiki iā ia ke mālama i kahi puka alapine paʻa i nā wela like ʻole.
2. Kiʻekiʻe alapine paʻa: OCXO maʻa mau loa pololei alapine paʻa, kona alapine deviation mea uuku a me ka paʻa.Hana kēia i ka OCXO kūpono no nā noi me nā koi alapine kiʻekiʻe.
2. ʻO 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.
3. 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.
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.
