GSF Modulator

GSF 860

Catvision GSF Modulator GSF 860 employes the GSM technology to ensure all harmonics fall above 900MHz, outside the TV band, thus providing flawless picture over long distances. It uses GaAs MMICs for high quality picture and sound with high C/N. The GSF 860 is specially designed for large CATV networks. A Microcontroller with latest PLL design gives it high precision and solid stability.
