Imoduli ye-DTV-3517B DVB-(T) iyidivayisi enemisebenzi eminingi enikeza izici eziningi ezithuthukile. Isekela okokufaka kweshuna engu-2S/S2, okokufaka okungu-10MHz/loop out, kanye ne-1PPS input/loop out, kanye ne-DVB-(T) RF ephuma kudivayisi eyodwa, i-multi-booting, ne-IP (1MPTS phezu kwe-UDP) isibuko sokukhishwa kwe-RF. Ngaphezu kwalokho, i-modulator isekela i-MISO ne-SISO ngokukhipha ukusebenza okuphezulu, okufana ne-MER>43dB, izinga lehlombe>56dB.

 

Idivayisi iza ne-crystal oscillator yezinga lokushisa engashintshi, enikeza ukufika kokuzinza okungu-0.1ppm. Iphinde ibe nesibonisi se-LCD nekhibhodi ukuze isebenze kalula. I-FMSUER DTV-3517 inamachweba okokufaka angu-4 we-ASI nokokufaka okungu-1 kwe-IP ngaphezu kwephrothokholi ye-UDP. Isekela i-10MHz okokufaka/i-loop out kanye ne-1PPS yokufaka/i-loop out, kanye ne-DVB-(T) RF ephuma kudivayisi eyodwa ne-PLP eyodwa. I-modulator iphinde isekele i-MISO ne-SISO, kanye nemodi yenetha ye-MFN.

 

Ngaphezu kwalokho, imoduli ye-DTV-3517/B isekela ukuhlanekezela kwangaphambili kwedijithali (DPD) okungaqondile nomugqa futhi inezici zokudlula ze-PID nezici zokudlula. Ingathuthukiswa futhi ilawulwe ngohlelo lokuphatha inethiwekhi olusekelwe kuwebhu, okuyenza ilungele ukumisa inethiwekhi yokusakaza yedijithali nokuhlinzeka ngezimpawu ezinhle zelabhorethri yesayensi kanye ne-DVB-(T) STB.

 

Sekukonke, imoduli ye-DTV-3517/B DVB-(T) iyisixazululo esinokwethenjelwa nesisebenzayo sokuguqula amasignali abe yi-DVB-(T) RF okukhiphayo. Izici zayo ezithuthukile nokusebenziseka kalula zikwenza kube ukukhetha okuhle kakhulu kokusakaza nezinye izinhlelo zokusebenza ezihlobene.

 

Ikhona futhi esitokweni:
