Qam Modulator
Jul 28, 2016
DIBSYS QAM6248 yog ib tiam tshiab Multi-functional QAM modulator, uas yuav tau txais ib channel rau TS ntawm tus IP interface los ntawm 16 raws ntawm TS ntawm ASI interfaces, thiab ces multiplex, nthee thiab ntau-modulate nrog channel coding, raws li tej plaub raws ntawm tus IP voj tso zis. Nws adopts peb tsim tshiab khiv zog xws li "Module tswj", scrambling, ntaus ntawv thiab channel tes taws los piav. Saj zawg zog customization thiab cov expansibility siab yuav los siav tus tam sim no thiab yav tom ntej DTV lawv raws.
Cov khoom no mas koj yuav lub DTV network taub hau kawg chav, ntug DTV qaum network, thiab DTV ceg kawg lub taub hau rov.
Feature
Txhawb ITU-T J.83A/B/C, tso zis ntau zaus ntau yam: 54MHz ~ 870 MHz
Txog li ASI 6/8/16 8 FTA dvb-s2 RF ports los yog GbE tus IP chaw nres nkoj hauv ib chassis uas Max.4 agile QAM raws tawm
Simultaneous outputs ntawm MPTS tus IP GbE thiab RF chaw nres nkoj
Muaj kev koom tes nrog 16QAM, 32QAM, 64QAM, 128QAM, 256QAM tes taws los piav kev peev
Tus ntaus ntawv xwb muaj ntau yam configurations, cov kev tso cai ntawm scrambling thiab RF cov zis tej channel yuav txiav txim los tso cai software
Txhawb simul-crypt 4 li CAS thiab DVB-CSA scrambling
Txhawb nws pib-tiam SI/PSI thiab lawm uploading thaum rov multiplexing
Nws pib-cim yug los yog kev tuav editing ntawm network ntaub ntawv, thiab raws li lub network lus sectors uploading
Txais yuav loj nrau nrog cache nco rau ob qhov thiab inconstant input ntsis kwj ntawm ASI interface
Saj zawg zog network configuration, yug input kwj nrhiav kom pib thiab cov neeg siv configuration txuag nws pib
188/204 cov ntaub ntawv tuaj rau lawv ntev, thiab zaub real-time cov hom ntawv ntawv
Kev txiav disease PID filtering, kuas pass-through
Yog siv PCR pib-kho lus
Tom tus nqi ntau yam ntawm cov ntaub ntawv tso zis ntau lawm xwb: 15.5 ~ 51.6Mbps
Cov zis tej ntaub ntawv cim tus nqi ntau yam ntawm tib RF channel: 4.2 ~ 7Mbaud/s
Tso zis ntau EPL: 95 dBuV ~ 115 dBuV (8 raws, raws li cov kauj ruam: 0.25 dB)
Txhawb koj qhov nce fine-tune paab es hauv-ntsuas, ntau yam hloov li cas lawm EPL EPL:-2.5 ~ 10.5 dB
Txhawb - 20dB RF kuaj chaw nres nkoj
Mus txog qhovtwg lim Circuit Court tsim kom koj tawm-ntawm-qhab rejection
Txhawb ntaus configuration ntshuam/export
Yooj yim rau-siv lawv tswj Web/SNMP-raws li tswj thiab hloov tshiab nyob rau hauv tej thaj chaw deb
Txuj kev ncau ntau lingual tswj neeg interfaces thiab lwm yam ntaub ntawv, nplua rau ob lub regional thiab teb chaws ciaj uas muag
Saib xyuas lag luam kub thiab hwj huam mov rau lawv.
