UHF Transmitter DTX 10000U

Features Supports DVB-T/H standards LDMOS Power Amplifier Output RF power 1 KW Integrated GPS Receiver UHF Up Converter Digital Precorrection SFN support Remotely manageable via SNMP Overview The High Power UHF Transmitter system DTX-10000U includes one to four independent UHF transmitters, designed to provide Digital Terrestrial Television Broadcasting service over the UHF frequency band from 470 MHz up to 860 MHz at the maximum output RF power level of 1000 Watts rms. each. The transmitters are installed in one 19" cabinet, 24U or 42U high. Each UHF Transmitter performs the conversion of the input MPEG transport stream to a COFDM modulated IF signal, converts this IF signal to the required transmit channel RF frequency within the UHF band and provides RF signal amplification up to the required output power level. The power level stability at the transmitter RF output is maintained by an internal automatic level control loop. The Modulator units inside the DTX-10000U operate according to the DVB-T/H modulation standards. The operation parameters of each Transmitter are monitored and controlled by the embedded system controller, located inside the corresponding Modulator section. The Transmitter control interfaces are located on the Modulator units and consist of: the front panel display, the local RS 232 serial port and the USB port (supporting CLI control line interface) and the 10/100/1000 Base-T Ethernet (protocols supported: WEB, Telnet and SNMP). All the Transmitter system components are enclosed in a standard 19" rack mount chassis, occupying 24 or 42 RU" of cabinet space. Each transmitter module (subassembly) has internal fans for coolin
