Ukuchazwa Komkhiqizo
Ukubuka okufushane
I-SR812ST (R) iyisiqalo sethu sakamuva se-Catv ebanga eliphakeme kakhulu I-Pre-Amplifier yamukela i-Full-Gaas MMIC, i-Post-Amplifier yamukela imodyuli ye-GAAS. Idizayini yesifunda eyenziwe kahle ehlanganiswe neminyaka yethu eyi-10 yesipiliyoni sokwakhiwa kobuchwepheshe, yenza imishini ifinyelele izinkomba ezinhle zokusebenza. Ukulawulwa kwe-Microprocesser, ukuboniswa kwedijithali kwamapharamitha, ukulungiswa kobunjiniyela kulula kakhulu. Yimishini esemqoka yokwakha inethiwekhi ye-catv.
Izici Zokusebenza
- I-Photo Real Pin Photoelectric Tonversic Tube.
- Kwenzelwe ukwakheka kwesifunda, ukukhiqizwa kwenqubo ye-SMT, kanye nendlela eyenziwe kahle yesiginali yenza ukuhanjiswa kwesiginali yezithombe zibushelelezi ngokwengeziwe.
- I-Chip ekhethekile ye-RF Attenuation, enezinto ezinhle ze-RF kanye ne-equilibrium linear, ukunemba okuphezulu.
- Idivaysi ye-Gaas Amplifier, amandla akhishwa kabili, ngokuthola okuphezulu nokuhlanekezela okuphansi.
- Imishini yokulawula i-single chip microcomputer (SCM) yokulawula okusebenzayo, i-LCD ikhombisa amapharamitha, lula ukusebenza okubonakalayo, nokusebenza okuzinzile.
- Ukusebenza okuhle kwe-AGC, lapho uhla lwamandla kagesi obonakalayo lungu -9 ~ + 2DBM, izinga lokukhipha ligcina lingashintshiwe, kanye ne-CTB ne-CSO ngokuyisisekelo kungashintshiwe.
- Isikhombimsebenzisi sokuxhumana sedatha esigciniwe, singakwazi ukuxhumana ne-Class ⅱ Inethiwekhi Management Response, kanye nokufinyelela ohlelweni lokuphathwa kwenethiwekhi.
- Ukubuyela emuva kungakhetha imodi yokuqhuma ukuze kunciphise ngokuqinile i-Noise Concesence futhi kunciphise inombolo yethomuli yangaphambili.
Izimo zokuhlola izixhumanisi
Amapharamitha wezobuchwepheshe ale ncwadi ngokuya ngendlela yokulinganisa ye-GY / T 194-2003
1. Ingxenye ye-Optical Want Optical: nge-10km ejwayelekile ye-fiber optical, i-passical optical attecuator, kanye ne-standard transmitic evamile yaqamba isixhumanisi sokuhlola. Setha isiteshi sesiteshi se-Analog ye-59 Pal-D-DAL-D enanini lama-45 / 87mhz ~ 550mhz ngaphansi kokulahleka kwesixhumanisi okubekiwe. Dlulisa ukuguqulwa kwedijithali kwe-modal ku-550mhz ~ 862 / 1003mhz, izinga lesiginali yedijithali (ku-8 MHz Bandwidth) yi-10DB ephansi kune-analog yesiginali yenethiwekhi. Lapho amandla okufaka okufakwayo we-Optical Optiveriver i-2dbm, izinga lokukhipha i-RF liyi-108dbbv, linokukhipha okungu-9db, ukukala i-C / CTB, c / CSB, kanye ne-C / N.
2. Ingxenye yangemuva ye-Optical transmit
QAPHELA: Lapho izinga lokukhishwa kwemali elilinganiselwe licushwa ngokuphelele uhlelo kanye namandla we-Optical are -2dbm, imishini ihlangabezana nezinga lokukhipha eliphakeme lenkomba yesixhumanisi. Lapho ukumiswa kwesistimu kunciphisa (okungukuthi, iziteshi zangempela zokuhambisa zinciphisa), izinga lokuphuma kwemishini lizokwandiswa.
