Gg-16MA 16 i le 1 modulator agile Analog CATV Headend
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.
Taitasi modulator e vaai filtered ma e seti gaosi i le auala manao ma aveesea tatau. ua tausia taimi tonu ma circuitry PLL. E ofoina faatinoga vitio e sili ona lelei ma le faatuatuaina sili i fata 4U.
MATAUPU
1. Easy faatulagaga, Internal ili mo modulators cooling
2. na o le tasi o galuega faatino RF. E le tatau combiner
3. pulea taimi tonu ma circuitry PLL
4. taitasi modulator ei ai lona vaega pulea
5. Avanoa i NTSC, ma configuration uo uma
