FALCOM MW 963 modulator is a fixed channel modulator using three SAW filters circuits thus it can respond to the VSB (Vestigial Side Band) frequencies. This device has a high level stability and optimization. Video and audio frequencies circuits are built integrated in the PLL control circuit, thus it can provide high accuracy. The device also has video and audio modulated RF carrier signal in the frequencies range of 45 – 860 MHz. The Falcom MW963 modulator can receive audio video signal source from satellite receivers, video tape recorders, digital DVD/VCD players, and other similar equipment which has audio video composite output. That makes FALCOM modulator 963 MW has the optimum standards and features for MATV / CATV system.

Features
