Sharraxaadda Wax soo saarka
Guudmar kooban
SR812ST (R) waa labadeena ugu dambeysay ee laba-badeedka ugu dambeysay ee laba-nooc ee ugu dambeeyay ee shabakadda 'Botch' ee Catv Classv. Hore-ka-cod-weyne wuxuu qaatay gasa MMIC-GOAS MMIC, Post-Colling Post wuxuu qaatay module Gaas. Qaab dhismeedka wareegga ee la wanaajiyo oo ay weheliso 10 sano oo khibraddeena naqshadeeye xirfadeed, ka dhig qalabka inuu gaaro tusaalayaal waxqabadka wanaagsan. Xakamaynta Microprocessor, Muujinta Dijital ah ee xuduudaha, dib-u-dejinta injineernimada ayaa si gaar ah u fudud. Waa qalabka ugu weyn ee lagu dhisayo shabakadda CATV.
Astaamaha waxqabadka
- Soocelinta jawaabta sare PIN-ka shaashadda sawirka.
- Qaabeynta Qulqulka Qulqulka, Soosaarka Nidaamka SMT, iyo dariiqa calaamadaha ee loo habeeyey ayaa ka dhigaya gudbinta calaamadaha sawirka sawir-qaade si ka sii siman.
- Cabsida la-talinta ee RF ee takhasuska leh, oo leh rf fiican oo rf iyo toosan oo toosan, sax ah.
- Gacmo-aaladda gas, oo labanlaab ah wax soosaar ah, oo leh faa'iido sare iyo dhalanrog hoose.
- Qeyb keli ah chip-ka ah qalabka kontoroolka (SCM) ee shaqeeya, LCD ayaa soo bandhigaya cabirrada, ku habboonaanta iyo hawlgalka dareenka dareenka, iyo waxqabadka xasilloon.
- Waxqabadka aad u fiican ee AGC, marka tirada ugu badan ee fikradda ay tahay -9 + 2dbm, heerka wax soo saarka ayaa is beddelaya, iyo CTB iyo CLBE asal ahaan isma beddelin.
- Interface isgaarsiinta macluumaadka ee loo qoondeeyay, waxay kuxiran kartaa fasalka ⅱ Jawaab bixiyaha maaraynta shabakadda, iyo marin u helka nidaamka maaraynta shabakadda.
- Soo celinta waxay xulaxi kartaa qaabka qulqulka si aad u yaraato isu-imaatinka qaylada oo yareynaya nambarka qaataha hore.
Xaaladaha tijaabinta
Cabirrada farsamada ee buug-gacmeedkan iyadoo la raacayo habka cabbiraadda ee Gy / T 194-2003
1. Howlgalka hore ee loo maro U deji 59 pal-D analog tv analog TV-ga ah oo kala duwan oo ah 45 / 87mhz ~ 550mhz oo hoos yimaada isku xirka la cayimay. U gudbi calaamadaha isbadalka dhigga ah ee ah 550mhz ~ 862 / 1003mhz, heerka calaamadaha dijital ah ee dhijitaalka ah (8 mHz xargaha) waa 10db ka hooseeya heerka xamuulka analogga. Marka fikradda indhaha ee soo-jeedinta indhaha ee qaataha optical ay tahay -2dbm, heerka wax soo saarka ee RF waa 108dBB Mist, oo cabir ka soo baxaan C / CTB, C / CSO, iyo C / n.
2. Qeybta Tooska ah ee Dhabarka: Xisaabinta Flatness iyo Ranges Flatness iyo Range Frysic oo NPR ah ayaa ah tilmaamaha isku xirka oo ka kooban dhameystirka indhaha gadaal iyo dhabarka gadaal.
Xusuusin: Marka heerka heerka wax soo saarka lagu qiimeeyo uu yahay qaabeynta nidaamka oo dhan iyo awoodda indhaha ee helka indhaha ayaa ah -2dbm, qalabku wuxuu la kulmayaa heerka ugu badan ee wax soo saarka ee iskuxirka. Marka qaabeynta nidaamka ay yareynayso (taasi waa, kanaalada saxda ah ee gudbinta dhabta ah waxay yareeyaan), heerka wax soo saarka wax soo saarka ayaa la kordhin doonaa.
