GG-16MA 16 in 1 Analog CATV Headend agile modulator
Short Description:
GG-16MA 16 in 1 Analog CATV Headend agile modulator
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.
Each modulator is SAW filtered and is factory set to the desired channel and proper offset. Precise frequency is maintained with PLL circuitry. It offers excellent video performance and high reliability in 4U rack.
FEATURES
1. Easy setup, Internal fans for cooling modulators
2. Only one RF output. No need combiner
3. Precise frequency control with PLL circuitry
4. Each modulator has its control panel
5. Available in NTSC, and all PAL configuration
