QPSK TO QAM Modulator Превземи спецификација

QPSK TO QAM Modulator is a new compact (1RU only) chassis and cost-effective multifunctional QAM modulator which supports QPSK demodulation, inputting remultiplexing. QPSK TO QAM Modulator has 2 ASI inputs (Max. bit rate of each channel up to 108Mbps), 2 QPSK inputs and one ASI output after re-multiplexing, one IF and RF testing output. The QPSK TO QAM Modulator has very convenient and friendly management interface, the user can complete all operation via local keyboard and LCD display on device, or access through the Ethernet port on device.
