Sharaxaadda Badeecada
1. Soo Koobidda Badeecada
SA1300CQalabka kor u qaada ee laba-jiho ee dibadda ee taxanaha ah waa qalabka kor u qaada ee cusub ee horumarsan. Naqshadeynta wareegga ee bisil iyo kuwa la hagaajiyay, habka gudaha ee cilmiyaysan iyo macquulka ah iyo agab tayo sare leh, waxay hubinayaan faa'iidada deggan iyo qallooc yar. Waa doorashada ugu fiican ee lagu dhisi karo shabakadda gudbinta laba-jiho ee CATV ee weyn ama dhexdhexaadka ah.
2. Astaamaha Waxqabadka
- Marxaladda hore ee waddada hore waxay qaadanaysaa module-ka amplifier-ka ugu cusub ee la soo dejiyo ee buuqa yar ee riix-jiidista ama module-ka riix-jiidista GaAs, marxaladda wax soo saarku waxay qaadanaysaa tusmada sare ee ugu cusub ee la soo dejiyo ee labanlaabka ahyModule amplifier ama module amplifier GaAs. Tusmada aan tooska ahayn waa wanaagsan tahay heerka wax soo saarkuna waa mid aad u deggan. Waddada soo celinta waxay qaadataa module amplifier-ka soo celinta ee ugu cusub ee tusmada sare ee la soo dhoofiyay. qallooca ayaa hooseeya saamiga calaamadda iyo buuqana waa mid sarreeya.
- Way ku habboon tahay in la saxo khaladaadka sababtoo ah shaandhada laba-laaban ee ku xiran, barbardhigga iyo attenuator-ka go'an (ama la hagaajin karo), iyo dekedaha ogaanshaha ee sayniska iyo macquulka ah ee khadka tooska ah.
- Qalabku wuxuu si joogto ah u shaqeyn karaa muddo dheer iyadoo xaalad deegaan oo xun ay ka jirto dibadda. Sababtoo ah guryaha aan biyuhu karin ee aluminiumka ah, korontada beddelka oo la isku halleyn karo oo sare iyo nidaamka ilaalinta hillaaca oo adag.
- Qolofku wuxuu qaataa naqshad moodeel ah oo ku dhex jirta; dayactirka qalabka, beddelka, iyo hagaajinta khaladaadka ayaa ku habboon.
3. Tilmaamaha Dalbashada
Fadlan xaqiiji: inta jeer ee la kala qaybinayo kor iyo hoos u xidhka wadooyinka laba-jiho ah.
4. Talooyin Gaar ah:
- Kahor intaadan isticmaalin badeecaddu waa inay ahaataa saldhig la isku halleyn karo!
- Awoodda ugu badan ee xad-dhaafka ah ee badeecadu waa 10A.
