FMUSER DTV-3517/-B 2/4 ASI/DVB-S/S2 1 IP(UDP) in DVB-T/T2 RF/IF Modulator

 

 

 

Overview:

FMUSER DTV-3517B DVB-(T) modulator is an all-in-one device that integrates demodulation; trans-mux; and modulation in one case to convert signals into DVB-(T) RF output and IP output over UDP. 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.

 

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.

 

 

 

Features:

FMUSER DTV-3517B:

The DTV-3517B 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.

 

The modulator supports MISO and SISO; with high performance output: MER>43dB; shoulder level>56dB. It features a constant temperature crystal oscillator with up to 0.1ppm stability and supports LCD display and keyboard.

 

FMUSER DTV-3517:

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.

 

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.

 

Overall; the DTV-3517/B 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.
