Sharaxaadda Badeecada

1. Soo Koobidda Badeecada

SR812S waa qaataha indhaha ee shabakadda CATV ee caalamiga ah oo leh qalabka maaraynta shabakadda. Qalabka hore u shaqeeya wuxuu qaataa amplifier-ka MMIC oo dhan, amplifier-ka dambena wuxuu qaataa module-ka amplifier-ka awoodda GaAs ee labanlaabka ah. Naqshadeynta wareegga ee la hagaajiyay, oo ay weheliso khibraddayada naqshadaynta RF ee xirfadleyda ah ee sannadaha ah, qalabku wuxuu gaaraa tusmada waxqabadka sare. Waa nooc ku habboon shabakadda CATV.

2. Muuqaalka

- Tuubada beddelka sawirka korontada ee PIN-ka oo jawaab celin sare leh, naqshadda xawaaraha 1G.
- Hoos u dhigista iyo simidda waxay noqon karaan nooc buro ah oo si joogto ah loo hagaajin karoama geli nooca. (Ikhtiyaar)
- Wax soo saarka labajibbaaran ee awoodda leh, faa'iido sare iyo qallooc hoose.
- Xakamaynta AGC ee indhaha, marka kala duwanaanshaha awoodda indhaha ee la geliyo ay tahay －7～＋2dBm, heerka wax soo saarku asal ahaan isma beddelin.
- Transponder shabakad ikhtiyaari ah, taageero nidaamka maaraynta shabakadda NMS.
