The modulator is equipped with 2 DVB-S/S2 tuner inputs; one GPS 10MHz input port; and one 1PPS input port. The output modulated signals are designed to be received by TVs; STBs; and other related devices. The modulator also supports adaptive linear and nonlinear digital pre-distortion and BISS function to descramble programs from the tuner input.&nbsp;FMUSER DTV-3517 DVB-(T) modulator is a new product that fully complies with the EN300 744 standard. The modulator features advanced modulating technology that effectively makes use of ground spectrum resources and provides reliable signals for fixed; mobile; and portable devices. Compared with DVB-T; the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold.&nbsp;&nbsp;&nbsp;<h2>Features:</h2><h2> FMUSER DTV-3517B:</h2>The DTV-3517B&nbsp;supports 2S/S2 tuner input; 10MHz input/loop out; and 1PPS input/loop out. It also supports DVB-(T) RF out in one device; multi-booting; and IP (1MPTS over UDP) mirror RF output.&nbsp;The modulator supports MISO and SISO; with high performance output: MER&gt;43dB; shoulder level&gt;56dB. It features a constant temperature crystal oscillator with up to 0.1ppm stability and supports LCD display and keyboard.&nbsp;<h2>FMUSER DTV-3517:</h2>FMSUER DTV-3517 has 4 ASI input ports and 1 IP input over UDP protocol. It also has 10MHz input/loop out and 1PPS input/loop out. The modulator supports DVB-(T) RF out in one device and single PLP. It also supports MISO and SISO; as well as MFN net mode. The modulator supports non-linear and linear digital pre-distortion (DPD) and features a constant temperature crystal oscillator with up to 0.1ppm stability.&nbsp;In addition; the modulator supports PID bypass and passthrough; with keyboard operation and LCD display. It can also be upgraded and controlled through a web-based network management system; making it ideal for setting up a digital broadcasting network and providing good signals for scientific laboratory and DVB-(T) STB.&nbsp;Overall; the DTV-3517/B&nbsp;DVB-(T) modulator is a reliable and efficient solution for converting signals into DVB-(T) RF output. Its advanced features and ease of use make it an excellent choice for broadcasting and other related applications.&nbsp; <img style="margin-left:auto;margin-right:auto;" data-srcid="-" src="https://image.doba.com/dgd1-PJvdzNybaebg/fmuser-dtv-3517-b-24-asidvb-ss2-1-ipudp-in-dvb-tt2-rfif-modulator.jpg" alt="dropship FMUSER DTV-3517/-B 2/4 ASI/DVB-S/S2 1 IP(UDP) in DVB-T/T2 RF/IF Modulator" /> &nbsp;<h2 align="justify">Principle Chart:</h2><h2 align="justify">&nbsp;</h2><h2 align="justify">FMUSER DTV-3517B</h2><h2 align="justify">&nbsp;</h2><h2 align="justify"> <img style="margin-left:auto;margin-right:auto;" data-srcid="-" src="https://image.doba.com/dgd1-YvqciShFaKbg/fmuser-dtv-3517-b-24-asidvb-ss2-1-ipudp-in-dvb-tt2-rfif-modulator.jpg" alt="dropship FMUSER DTV-3517/-B 2/4 ASI/DVB-S/S2 1 IP(UDP) in DVB-T/T2 RF/IF Modulator" /> FMUSER DTV-3517 &nbsp;</h2><img data-srcid="-" src="https://image.doba.com/dgd1-cKqdySmltFbA/fmuser-dtv-3517-b-24-asidvb-ss2-1-ipudp-in-dvb-tt2-rfif-modulator.jpg" alt="dropship FMUSER DTV-3517/-B 2/4 ASI/DVB-S/S2 1 IP(UDP) in DVB-T/T2 RF/IF Modulator" />&nbsp;<h2 style="text-align:left;" align="center">Specification:</h2><h2 align="center"> FMUSER DTV-3517B</h2><table style="height:399px;" border="1" cellspacing="0"><tbody><tr style="height:21px;"><td style="width:255.641px;height:84px;text-align:center;" rowspan="4" valign="center">Input</td><td style="width:950.359px;height:21px;" colspan="3" valign="top">2*S/S2 Tuner input</td></tr><tr style="height:21px;"><td style="width:950.359px;height:21px;" colspan="3" valign="top">10MHz reference clock input and loop out;
