Te Oscillator Karaihe Whakahaere-ā-Umu (OCXO)

Ko te Oven Controlled Crystal Oscillator (OCXO) he oscillator tioata e whakamahi ana i tētahi tāke pāmahana pumau hei pupuri i te pāmahana o te resonator tioata kuata i roto i te oscillator tioata pumau, ā, ka whakaitihia te huringa auau putanga o te oscillator i puta mai i te huringa pāmahana taiao ki te iti rawa. Ko te OCXO he mea hanga mai i tētahi ara iahiko whakahaere tāke pāmahana pumau me tētahi ara iahiko oscillator, e whakamahi ana i tētahi "piriti" thermistor he mea hanga mai i te whakakaha raupapa rerekētanga hei whakatutuki i te whakahaere pāmahana.

Ko ēnei ōna āhuatanga:

1. Te kaha o te mahi whakatikatika pāmahana: Ka whakatutukihia e te OCXO te whakatikatika pāmahana ki te oscillator mā te whakamahi i ngā huānga pūoko pāmahana me ngā ara iahiko whakau. Ka taea e ia te pupuri i te putanga auau pumau i ngā pāmahana rerekē.
2. Te pumau o te auau teitei: He tino tika te pumau o te auau o te OCXO, he iti te rerekētanga o te auau, ā, he āhua pumau. Nā tēnei ka pai te pumau o te auau teitei o te OCXO mō ngā tono e hiahiatia ana he auau teitei.
3. Wā tīmatanga tere: He poto te wā tīmatanga o te OCXO, he torutoru mirihekona noa iho, ka taea ai te whakau tere i te auau putanga.
4. He iti te kaha e pau ana: He iti ake te kaha e pau ana i ngā OCXO, ā, he pai mō ngā tono he tino kaha ake ngā whakaritenga mana, ka taea ai te penapena i te kaha pākahiko.

Ngā Whakamahinga o ngā Oscillators Crystal Controlled Oumu:

1. Ngā pūnaha whakawhitiwhiti kōrero: E whakamahia whānuitia ana te OCXO i roto i te whakawhitiwhiti kōrero pūkoro, te whakawhitiwhiti kōrero amiorangi, te tuku raraunga ahokore me ētahi atu mara hei whakarato i te auau tohutoro pumau.
2. Ngā pūnaha tūnga me te whakatere: I roto i ngā tono pēnei i te GPS me te Pūnaha whakatere Beidou, ka whakamahia te OCXO hei whakarato tohu karaka tika, kia taea ai e te pūnaha te tatau tika i te tūnga me te ine i te wā.
3. Ngā Taputapu me ngā Mea Ine Tika: I roto i ngā taputapu me ngā taputapu ine tika, ka whakamahia te OCXO hei whakarato i ngā tohu karaka tika hei whakarite i te tika me te taea te tāruarua o ngā hua ine.
4. Taputapu hiko: E whakamahia whānuitia ana te OCXO i roto i te ara iahiko karaka o ngā taputapu hiko hei whakarato i te auau karaka pumau kia taea ai te mahi noa o te taputapu.

I te poto, ko ngā āhuatanga o te OCXO ko te kaha o te mahi whakatikatika pāmahana, te pumau auau teitei, te tere o te wā whakaoho me te iti o te whakamahinga hiko, he mea e tika ana mō ngā tono me ngā whakaritenga auau teitei me te tairongo ki ngā huringa pāmahana o te taiao.
