Sharaxaada Alaabta
1. Soo koobida alaabta
SA1300Ccod-weyneeye jirrid laba jiho dibadda ah oo taxane ah waa cod-weyneeye faa'iido sare oo cusub oo horumarsan. Naqshad wareeg ah oo qaan-gaar ah oo la hagaajiyay, habka gudaha ee sayniska iyo macquulka ah iyo qalab tayo sare leh, hubi faa'iidada xasilloon iyo qallooca hooseeya. Waa doorashada ugu fiican ee lagu dhisayo isku-xidhka gudbinta labada jiho ee CATV weyn ama mid dhexe.
2. Tilmaamaha Waxqabadka
- Waddada hore ee marxaladda ka horreysa waxay qaadanaysaa tusmaynta sare ee ugu cusub ee la soo dejiyay moduleka cod-weyneeye-jiid-jiid hooseeya ama GaAs-jiid-jiid-jiid, heerka wax-soo-saarku wuxuu qaadanayaa tusmada sare ee cusub ee la soo dejiyay labanlaab.ymodule amplifier ama moduleka cod-weyneeye GaAs. Tusmada aan tooska ahayn ayaa wanaagsan, heerka wax soo saarkuna aad buu u deggan yahay. Jidka soo laabashada waxa uu qaadanayaa tusmada sare ee cusub ee soo celinta soo celinta u go'an moduleka cod-weyneeye Qalloocaa wuu hooseeyaa calaamada saamiga qayladana waa sarreeyaa.
- Way ku habboon tahay in la saxo sababta oo ah shaandhada laba-laabka ah ee plug-ka ah,-ku-gudbinta siman (ama la hagaajin karo) barbareeyaha iyo attenuator-ka, iyo dekedaha ogaanshaha ee sayniska iyo macquulka ah ee khadka.
- Qalabku waxa uu muddo dheer si joogto ah ugu shaqayn karaa dibadda xaalad xun oo deegaanka ah. Sababtoo ah guryaha aluminiumka ah ee aan biyuhu lahayn, isku hallaynta sare ee wareejinta tamarta iyo nidaamka ilaalinta hillaaca adag.
- qoloftu waxay qabataa naqshad qaabaysan oo isku dhafan; dayactirka qalabka, beddelka, iyo ka saarista ayaa ku habboon.
3. Tilmaamaha Dalbashada
Fadlan xaqiiji: kor iyo hoos isku xidhka kala qaybinta inta jeer ee wadooyinka laba jiho.
4. Talooyin gaar ah:
Kahor inta aan la isticmaalin badeecada waa in ay noqotaa mid la isku halayn karo!
- Awoodda xad dhaafka ah ee ugu badan ee alaabtu waa 10A.
