GG-16MA 16 di 1 Analog CATV Headend modulator çalakbûna
Short Description:
GG-16MA 16 di 1 Analog CATV Headend modulator çalakbûna
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.
Her modulator SAW filtrata e û set factory ji bo ku kanalê bi xwestin û durust (balansek) e. frequency yeqîn e bi circuitry PLL parast. Ew ji bo performansa video baş û bawerîpêkirina bilind li rack 4U.
FEATURES
1. setup Easy, fans Navxweyî ji bo modulators sar
2. Tenê yek encam RF. No combiner pêwîst
3. kontrol frequency Precise bi circuitry PLL
4. Her modulator heye kontrol panela xwe
5. Available li NTSC, û hemû veavakirina PAL
