Oscillator ya Crystal Controlled Oven (OCXO)

Oscillator ya Crystal Controlled Oven (OCXO) ni oscillator ya crystal ikoresha tanki y'ubushyuhe idahinduka kugira ngo ubushyuhe bwa quartz crystal resonator bugume mu gasanduku k'imashini ya crystal, kandi impinduka z'umuvuduko w'imashini ya crystal ziterwa n'impinduka z'ubushyuhe mu kirere ziragabanuka kugeza ku rugero ruto. OCXO igizwe n'agasanduku k'imashini igenzura ubushyuhe idahinduka n'agasanduku k'imashini ya crystal, ubusanzwe ikoresha "bridge" ya thermistor igizwe na amplifier y'uruhererekane rw'impinduka kugira ngo igenzure ubushyuhe.

Ifite ibi bikurikira:

1. Imikorere ikomeye yo kwishyura ubushyuhe: OCXO igera ku gipimo cy'ubushyuhe kuri oscillator ikoresheje ibintu bipima ubushyuhe n'imiyoboro ihamye. Ishobora kugumana umusaruro uhamye ku bushyuhe butandukanye.
2. Guhagarara neza kw'amajwi: OCXO ubusanzwe ifite ubushobozi bwo kuguma neza kw'amajwi, guhindagurika kwayo ni guto kandi guhamye. Ibi bituma OCXO ikoreshwa neza mu gukoresha amajwi afite ubushobozi bwo kugenda neza.
3. Igihe cyo gutangira vuba: Igihe cyo gutangira cya OCXO ni gito, akenshi ni milisegonda nke gusa, bishobora gutuma frequency y'ibisohoka ihagarara vuba.
4. Ingufu nke zikoreshwa: OCXO zisanzwe zikoresha ingufu nke kandi zikwiriye gukoreshwa mu buryo busaba ingufu zikomeye, zishobora kuzigama ingufu za batiri.

Imikoreshereze ya Oscillators za Crystal zigenzurwa n'Ifuru:

1. Sisitemu z'itumanaho: OCXO ikoreshwa cyane mu itumanaho rigendanwa, itumanaho rya satelite, kohereza amakuru adafite umugozi n'ahandi kugira ngo itange umurongo uhamye w'ifatizo.
2. Sisitemu zo gushyira imiterere y'ahantu n'uburyo bwo kugenzura: Muri porogaramu nka GPS na Beidou navigation System, OCXO ikoreshwa mu gutanga ibimenyetso by'isaha neza, bigatuma sisitemu ibarwa neza aho iri no gupima igihe.
3. Ibikoresho: Mu bikoresho n'ibikoresho bipima neza, OCXO ikoreshwa mu gutanga ibimenyetso by'isaha neza kugira ngo hamenyekane neza kandi ko ibisubizo byo gupima bigaruka.
4. Ibikoresho by'ikoranabuhanga: OCXO ikoreshwa cyane mu buryo bw'isaha y'ibikoresho by'ikoranabuhanga kugira ngo itange umurongo uhamye w'isaha kugira ngo igikoresho gikore neza.

Muri make, OCXO ifite imiterere yo kwishyura ubushyuhe bwinshi, kudahindagurika cyane, igihe cyo gutangira vuba no gukoresha ingufu nke, ibi bikaba bikwiriye porogaramu zikenera inshuro nyinshi kandi ziterwa n’impinduka z’ubushyuhe mu bidukikije.
