ZJ3308AT 8 gudaha 1 ATSC Modulator
Guudmarka alaabta
ZJ3308AT 8 ee 1 ATSC modulator waa badeecad dhowaan loo qaabeeyey oo taageeraya gelinta IP-ga. Waxay leedahay 8 kanaal isku dhufasho badan iyo 8 ATSC Kanaal wax ka beddela, waxayna taageertaa ugu badnaan 256 IP gelinta dekedda GE. ZJ3308AT waxay leedahay awood wax soo saar awood leh oo leh 8 sideyaal aan u dhaweyn (50MHz ~ 960MHz) soo saar iyada oo loo marayo sheyga wax soo saarka RF. Nidaamka qalabkani wuxuu noqon karaa khad la kontoroolo isla markaana lagu casriyeeyo shabakad, taas oo si weyn loogu isticmaali karo ATSC dejinta shabakada baahinta dhijitaalka ah iyo tijaabinta loogu talagalay ATSC dejinta nambarka sare.
Astaamaha Muhiimka ah
