DTT5900-10H 100Htus kws tshaj lij DVB-T / ATSC / ISDB-T digital transmitter, uas muab lub zog tso tawm, nrog 10W / 100W fais fab kev xaiv. Nws compact qauv tsim tau zoo heev txuag chaw rau koj chav. Qhov ntau zaus ntawm DTT5900 yog los ntawm 470MHz ~ 806MHz, nws muaj cov kab tawm siab thiab kev ntseeg siab vim nws yuav siv sij hawm siab thiab siab linear LDMOS raj amplifier module. Tsis tas li ntawd, nws txhawb nqa AGC muaj nuj nqi kom muaj zog tso zis.

DIBSYS yeej ib txwm npaj ua kom tau raws li cov neeg siv khoom xav tau los ntawm kev ua kom nws muaj peev xwm tso zis hluav taws xob lossis ntau tus neeg nqa khoom, hloov mus rau cov teeb liab channel thiab kev sib kis dav dav. Peb ua txhua qhov xav tau DVB-T / ATSC / ISDB-T transmitter ntsuas, los ntawm kev kuaj pom thawj zaug rau lub transmitter, mus rau kev ntsuas thaum lub sij hawm commissioning thiab kev tiv thaiv txij nkawm.
