SR812st (r) yog peb cov qib siab kawg ob-tso zis catv network kho qhov muag. Lub ntej-amplifier adopts acc-gaas mmic, post-amplifier adopts adopts Adopts Gaas module. Kev Tsim Kho Circuit Couped nrog peb 10 xyoo ntawm kev tsim qauv kev paub, ua kom cov khoom siv ua tau cov khoom ua tau zoo. Microprocessor tswj, Digital zaub ntawm cov tsis muaj, lub tshuab nqus tsev envorugging yog qhov yooj yim heev. Nws yog cov khoom siv tseem ceeb los tsim lub Catv network.
Cov yam ntxwv ua tau zoo
- Muaj lus teb siab Pin photoelectric hloov siab hloov tube.
- Kev tsim kho Circuit Court zoo, SMT txheej txheem tsim khoom, thiab optimized teeb liab txoj kev ua kom lub yees duab kos npe kis tau tus.
- Tshwj xeeb rf attenishing chip, nrog zoo rf attenuation thiab equilibrium linear, muaj qhov tseeb.
- Gaas amplifier ntaus ntawv, lub zog doubly tso tawm, nrog siab nce thiab qis distortion.
- Tib nti microcomputer (scm) tswj cov cuab yeej ua haujlwm, LCD qhia cov tsis ua haujlwm, kev ua haujlwm yooj yim thiab kev paub ua haujlwm.
- Kev ua kom zoo rau AGC zoo heev, thaum cov tswv yim tawm siv hluav taws xob ntau yog -9 ~ + 2DBM, qib tso zis tawm ua rau tsis hloov pauv, thiab CTB thiab CSO tsis hloov pauv.
- Muaj cov ntaub ntawv sib txuas lus sib txuas lus nrog, tuaj yeem txuas nrog chav kawm ⅱ kev ua haujlwm tswj hwm kev ua haujlwm, thiab kev nkag mus rau lub system tswj hwm network.
- Rov qab tawm tswv yim tuaj yeem xaiv cov kev tawg tawg kom nrawm dua rau cov suab nrov sib cav thiab txo cov lej ntawm kev ua kom puv nkaus.
Txuas Kev Ntsuas
Cov kev ntsuas ntawm phau ntawv no raws li kev ntsuas txoj kev ntawm GY / T 194-2003
1. Sab saum toj Optical tau txais Ntu: Nrog 10KM Txuj Ci Fiber Ntau, Passive Optical Hwj Pwm, thiab Txuj Ci System Composed Cov ntawv txuas. Teeb 59 Pal-d Analog TV channel teeb liab ntawm thaj tsam ntawm 45 / 87MHz ~ 550MHz nyob rau hauv qhov kev sim sib txuas. Xa cov teeb meem digital hloov ntawm thaj tsam ntawm 550MHz ~ 862 / 100MHz, cov teeb liab kev hloov pauv qib (hauv 8db qis dua li lub cim teeb liab. Thaum lub tswv yim kho qhov muag ntawm lub qhov muag tau yog -2Dbm, cov ntawv tso zis RF ua kom muaj 108dbμv, ntsuas C / CSB, C / CSO, thiab C / N.
2. Yav Tom Ntej Optical Transmmar thiab Link Ciaj thiab NPR cov ntsiab lus yog cov ntsuas txuas uas yog tsim ntawm lub nraub qaum rov qab kho dua tshiab thiab kho qhov muag rov qab.
Nco tseg: Thaum cov kev ntsuas ntsuas qib qib yog lub kaw lus tag nrho yog -2DBM, cov cuab yeej siv kho qhov muag tau ua tiav qib siab tshaj plaws ntawm kev sib txuas. Thaum lub kaw lus configuration txo (uas yog, qhov tseeb sib kis tau nce), cov zis ntawm cov khoom siv tau nce.
Tus phooj ywg ceeb toom: qhia koj teeb lub teeb liab rau 6 ~ 9DB tilt tso tawm hauv cov ntaub ntawv engineering los txhim kho tus lej nonlinear (hauv qab) ntawm cov cable system.
