Digital TV Headend QPSK Modulator,(DT-QPSKM) is developed according to DVB-S (EN300421) QPSK standard. It has powerful spectral
efficiency, advanced anti-jamming and competitive price-performance ratio. To guarantee the high transmission performance, this QPSK
modulator adopts the disposal of energy diffusing, RS coding, convolution interleaving and pre-modulated baseband shaping. To sum up,
all the approaches make this DT-QM-9401D QPSK modulator widely used in Broadcasting, Interactive Services, News Gathering and other
Broadband satellite applications.Power:AC 100-240V, 50Hz-60Hz 2A,Power Plug:European standard Plug or American standard Plug is optional.
