DVB-T Модулатор Превземи спецификација

DVB-T Modulator is made according to DVB-T standard output the RF signals, which can be transmitted through HFC and MMDS networks. It is widely used in digital TV, data broadcasting, VOD, Internet, video conference systems. The WDQ-3300 has very convenient management interface, the user can complete all operation via local keyboard and LCD display on device, or access through the Ethernet port on device.
