Overview

DUT-8351 is a professional DVB-T/ATSC/ISDB-T digital transmitter researched and developed by DEXIN, which gives sustained power output. Its compact structure design has greatly saved space for your room. It is applicable to both SFN and MFN network modes and supports both signal-carrier mode and multi carrier-mode. Signal channel and broadband transmission are supported. The frequency range of DUT-8351 is from 470MHz~806MHz. This transmitter has a very high linear and high reliability as it takes high gain and high linear LDMOS tube amplifier module. Furthermore, it supports AGC function to keep sustained power output. Key Features: Enhanced signal transmission quality; Intelligent and modularized amplifier unit, takes high power gain and high linear; LDMOS tube amplifier module design; Low power consumption and super linear design to improve the transmission power,; and reduce the nonlinear distortion; Support AGC function with sustained power output to allow the transmitter a good; stability and reliability; LED on the front panel support alarm and signal monitor; Stabilized-power supply with wide range of voltage and high efficiency
