The DTV-3517B DVB-(T) modulator is a versatile device that offers many advanced features. It supports 2S/S2 tuner input, 10MHz input/loop out, and 1PPS input/loop out, as well as DVB-(T) RF out in one device, multi-booting, and IP (1MPTS over UDP) mirror RF output. Moreover, the modulator supports MISO and SISO with high-performance output, such as MER>43dB, shoulder level>56dB.

The device comes with a constant temperature crystal oscillator, providing up to 0.1ppm stability. It also has an LCD display and keyboard for easy operation. The FMSUER DTV-3517 has 4 ASI input ports and 1 IP input over the UDP protocol. It supports 10MHz input/loop out and 1PPS input/loop out, as well as DVB-(T) RF out in one device and single PLP. The modulator also supports MISO and SISO, as well as MFN net mode.

In addition, the DTV-3517/B modulator supports non-linear and linear digital pre-distortion (DPD) and has PID bypass and passthrough features. It can 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.
