DTV-3517B DVB-(T) modulator ke sesebelisoa se feto-fetohang se fanang ka likarolo tse ngata tse tsoetseng pele. E ts'ehetsa 2S/S2 tuner input, 10MHz input/loop out, le 1PPS input/loop out, hammoho le DVB-(T) RF out in one device, multi-booting, le IP (1MPTS over UDP) mirror RF output. Ho feta moo, modulator e ts'ehetsa MISO le SISO ka tlhahiso e phahameng ea ts'ebetso, joalo ka MER> 43dB, boemo ba mahetla> 56dB.

 

Sesebelisoa se tla le oscillator ea mocheso oa kristale, e fanang ka botsitso ba 0.1ppm. E boetse e na le ponts'o ea LCD le keyboard bakeng sa ts'ebetso e bonolo. FMSUER DTV-3517 e na le likou tsa ho kenya tse 4 tsa ASI le ho kenya 1 IP holim'a protocol ea UDP. E ts'ehetsa 10MHz input/loop out le 1PPS input/loop out, hammoho le DVB-(T) RF e tsoa ka sesebelisoa se le seng le PLP e le' ngoe. Modulator e boetse e tšehetsa MISO le SISO, hammoho le mokhoa oa net oa MFN.

 

Ho phaella moo, modulator ea DTV-3517 / B e tšehetsa mokhoa o sa tsitsang oa digital pre-distortion (DPD) 'me o na le likarolo tsa PID le mokhoa oa ho feta. E ka ntlafatsoa le ho laoloa ka tsamaiso ea marang-rang e thehiloeng marang-rang, e leng se etsang hore e be se loketseng bakeng sa ho theha marang-rang a khaso ea digital le ho fana ka lipontšo tse ntle bakeng sa laboratori ea saense le DVB-(T) STB.

 

Ka kakaretso, modulator ea DTV-3517/B DVB-(T) ke tharollo e tšepahalang le e sebetsang ea ho fetolela matšoao ho DVB-(T) RF output. Likarolo tsa eona tse tsoetseng pele le boiketlo ba tšebeliso li etsa hore e be khetho e ntle haholo bakeng sa ho hasanya le lits'ebetso tse ling tse amanang.
