GG-16 16 ngo-1 CATV channel esisiGxina headend modulator
Inkcazo elifutshane:
GG-16M 16 ngo-1 CATV channel esisiGxina headend modulator
I GG-16M i 4RU yokubeka isisu semoto okubonakala ivumela ufakelo lamaqhosha ukuya ku-16 isilawuli-elawulwa ezisisigxina okanye inokusityeda, mini-modulators. combiner esebenzayo eyakhelwe-ngaphakathi ephelisa iingcingo ezihamab phantsi ngokungeyomfuneko uxhulumano lwe ngxaki ezinokubakho neqinisekisa kwinqanaba output eliphezulu.
Zonke modulators ugqibelele mveliso iseti kwiindlela ezinqwenelekayo nelifanelekileyo offset.
IIMBONAKALO
1. Ukutshintshela umbane yokuthamba nokufakwa ummiselo ombane ngqo
2. ezimbini iifeni zokupholisa ngenxa yokusebenza ubomi obude
3. Inqanaba chassis output 45dBmV, akukho mfuneko combiner engaphezulu
4. wabona (umphezulu ive wave) ukuhluza kwi IF for ongamile band C / N
5. Front ulawulo ukufikelela yolawulo yenza yababini lula
