GG-16MA 16 e 1 Analog CATV Headend modulator beshesha
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 ngamunye wabona elicwengekileyo futhi imboni isethi isiteshi oyifunayo futhi efanele offset. imvamisa eqondile inakekelwa nge PLL busebenze. It unikeza kakhulu isiqophi ukusebenza nokuthembeka okusezingeni eliphezulu e 4U yokubeka.
EZIPHUMA
1. Easy isethaphu, abalandeli Yangaphakathi ngoba modulators ukupholisa
2. Lilodwa RF okukhiphayo. Ayikho combiner isidingo
3. eqondile imvamisa isilawuli PLL busebenze
4. modulator ngamunye unegunya yayo iphaneli
5. Itholakala NTSC, futhi zonke ukucushwa PAL
