Modulator-ka DTV-3517B DVB-(T) waa qalab kala duwan oo bixiya astaamo horumarsan oo badan. Waxay taageertaa gelinta 2S/S2 tuner, 10MHz input/loop out, iyo 1PPS input/loop out, iyo sidoo kale DVB- (T) RF mid ka mid ah aaladaha, bootinta badan, iyo IP (1MPTS oo ka sarreeya UDP) wax soo saarka RF. Waxaa intaa dheer, modulator-ku wuxuu taageeraa MISO iyo SISO wax soo saar heer sare ah, sida MER> 43dB, heerka garabka> 56dB.

 

Qalabku wuxuu la socdaa oscillator heerkul joogto ah, kaas oo siinaya ilaa 0.1ppm xasilooni. Waxa kale oo ay leedahay shaashad LCD ah iyo kiiboodhka si fudud loogu hawlgalo. FMSUER DTV-3517 waxay leedahay 4 dekedood oo ASI ah iyo 1 galinta IP ee nidaamka UDP. Waxay taageertaa 10Mhz wax-gelinta/loop-ka-baxa iyo 1PPS-gelinta/loop-ka-baxa, iyo sidoo kale DVB-(T) RF hal qalab iyo hal PLP. Modulator-ku waxa kale oo uu taageeraa MISO iyo SISO, iyo sidoo kale qaabka saafiga ah ee MFN.

 

Intaa waxaa dheer, modulator-ka DTV-3517/B waxa uu taageeraa qalloocinta ka horeysa ee dhijitaalka ah ee aan toos ahayn iyo toosan (DPD) oo waxa uu leeyahay PID-ga gudubka iyo sifooyin maris. Waa la cusboonaysiin karaa oo lagu xakamayn karaa iyada oo loo marayo nidaamka maamulka shabakadaha ku salaysan, taas oo ka dhigaysa mid ku habboon samaynta shabakad baahinta dhijitaalka ah iyo bixinta calaamado wanaagsan oo loogu talagalay shaybaarka sayniska iyo DVB- (T) STB.

 

Guud ahaan, modulator-ka DTV-3517/B DVB-(T) waa xal la isku halayn karo oo hufan oo loogu beddelo calaamadaha DVB- (T) RF. Sifooyinkeeda horumarsan iyo adeegsigeeda fudud ayaa ka dhigaya doorasho aad u wanaagsan baahinta iyo codsiyada kale ee la xiriira.
