SR812ST(R) shine sabon mai karɓar gani na cibiyar sadarwar CATV mai inganci mai inganci biyu. Mai ƙara girman yana ɗaukar cikakken GaAs MMIC, mai ƙara girman yana ɗaukar tsarin GaAs. Tsarin da'ira mai kyau tare da shekaru 10 na ƙwarewar ƙira ta ƙwararru, yana sa kayan aikin su cimma kyakkyawan ma'aunin aiki. Kula da microprocessor, nunin dijital na sigogi, da gyara injiniyan suna da sauƙi musamman. Ita ce babban kayan aikin gina cibiyar sadarwar CATV.
Halayen Aiki
- Bututun canza wutar lantarki mai ƙarfi na PIN mai amsawa.
- Tsarin da'ira da aka inganta, samar da tsarin SMT, da kuma ingantaccen hanyar sigina suna sa watsa siginar photoelectric ya fi santsi.
- Ƙwararren guntu na rage RF, tare da kyakkyawan rage RF da daidaitaccen layi, babban daidaito.
- Na'urar ƙara ƙarfin GaAs, fitarwa mai ƙarfi sau biyu, tare da babban riba da ƙarancin karkacewa.
- Kayan aikin sarrafa Microcomputer guda ɗaya (SCM) suna aiki, LCD yana nuna sigogi, dacewa da aiki mai fahimta, da kuma aiki mai dorewa.
- Kyakkyawan aikin AGC, lokacin da ƙarfin wutar lantarki na gani ya kai ⼍9～＋2dBm, matakin fitarwa yana ci gaba da canzawa, kuma CTB da CSO ba su canzawa ba.
- Tsarin sadarwa na bayanai da aka adana, zai iya haɗawa da mai amsa cibiyar sadarwa ta aji Ⅱ, da kuma samun damar shiga tsarin gudanar da cibiyar sadarwa.
- Fitar da hayaki daga dawowa na iya zaɓar yanayin fashewa don rage yawan hayaniyar da kuma rage adadin mai karɓar gaba.
Yanayin Gwaji na Haɗin Hanya
Sigogi na fasaha na wannan jagorar bisa ga hanyar aunawa ta GY/T 194-2003
1. Sashen karɓar gani na gaba: tare da zare na gani na yau da kullun na 10km, na'urar rage haske mai aiki, da kuma na'urar watsa haske ta yau da kullun sun haɗa hanyar gwaji. Saita siginar tashar talabijin ta analog 59 PAL-D a kewayon 45/87MHz～550MHz a ƙarƙashin asarar haɗin da aka ƙayyade. Aika siginar daidaitawa ta dijital a kewayon 550MHz～862/1003MHz, matakin siginar daidaitawa ta dijital (a cikin bandwidth 8 MHz) yana ƙasa da matakin mai ɗaukar siginar analog. Lokacin da ƙarfin shigarwa na gani na mai karɓar gani ya kasance -2dBm, matakin fitarwa na RF shine 108dBμV, tare da karkatar fitarwa ta 9dB, auna C/CTB, C/CSO, da C/N.
2. Sashen watsa haske na baya: Daidaito tsakanin hanyoyin haɗin yanar gizo da kuma kewayon motsi na NPR sune ma'aunin hanyoyin haɗin yanar gizo waɗanda suka ƙunshi mai watsa haske na baya da mai karɓar haske na baya.
Lura: Idan matakin fitarwa da aka ƙima ya kasance cikakken tsarin tsarin kuma ƙarfin gani mai karɓa shine -2dBm, kayan aikin sun cika matsakaicin matakin fitarwa na ma'aunin haɗin. Lokacin da tsarin tsarin ya ragu (wato, ainihin tashoshin watsawa suna raguwa), matakin fitarwa na kayan aiki zai ƙaru.
Sanarwa Mai Kyau: Shawarar ku saita siginar RF zuwa fitowar karkatarwa ta 6 ~ 9dB a cikin aikace-aikacen injiniyan aiki don inganta ma'aunin mara layi (a ƙarƙashin ma'aunin) na tsarin kebul.
