ʻO ka FMUSER DTV3517 2-Channel DVB-T Modulator kahi mea paʻa a paʻakikī e hoʻohui i ka demodulation, trans-mux, a me nā hana modulation i hoʻokahi hihia. ʻAe kēia iā ʻoe e hoʻololi i nā hōʻailona i DVB-(T) RF a me ka hoʻopuka IP ma luna o UDP me ka maʻalahi. Hiki iā ʻoe ke hoʻohana i kēia hāmeʻa no ka loaʻa ʻana o nā hōʻailona mai 2 DVB-S/S2 tuner inputs, hoʻokahi awa hoʻokomo GPS 10MHz, a hoʻokahi awa hoʻokomo 1PPS. Hiki ke loaʻa nā hōʻailona modulated e nā TV, STBs, a me nā mea hana like ʻole.

 

Hoʻolako ʻia kēia modulator DVB-(T) me ka adaptive linear a me ka nonlinear digital pre-distortion, hiki iā ʻoe ke hoʻonui i kāu hoʻopuka hōʻailona. Loaʻa iā ia kahi hana BISS e hiki ke wehewehe i nā polokalamu mai ka hoʻokomo tuner. Me kēia hāmeʻa, hiki iā ʻoe ke hauʻoli i ka hopena kiʻekiʻe me MER>43dB a me ka pae poʻohiwi>56dB. Kākoʻo ka hāmeʻa iā MISO a me SISO me IP (1 * MPTS ma luna o UDP) aniani RF puka no ka hoʻohui ʻia.

 

ʻO ka FMUSER DTV3517 DVB-T Modulator e hele mai me ka oscillator kristal wela mau, e hōʻoia ana i ka paʻa kiʻekiʻe a hiki i 0.1ppm.
