GG-16MA 16 ngo-1 Analog CATV Headend modulator zikhululekile
The GG-16MA is a space saving, agile channel modulator systemic consists of 16 individual, vertically mounted, changeable frequency modulators and an efficient switching type power supply module. It is designed for 19” rack mounting.
modulator nganye Saw ecociweyo kwaye mveliso iseti kwijelo elifunekayo nelifanelekileyo offset. frequency Echanekileyo igcinwa kunye PLL busebenze. Inikeza ukwenza kwevidiyo egqwesileyo kunye nokuthembeka eziphakamileyo 4U yokubeka.
IIMBONAKALO
1. setup Easy, fans zangaphakathi modulators zokupholisa
2. enye kuphela output RF. Asikho isidingo combiner
3. Ulawulo frequency ngqo nge PLL busebenze
4. modulator nganye panel wakhe wolawulo
5. Efumanekayo ku NTSC, nabo bonke kwintanga yoqwalaselo
