The Master Video Agile Modulator MM303 is a frequency agile SAW filtered modulator for adjacent channel operation for broadcast or CATV channels from 50 to 300 MHz. Channel selection is done by convenient front panel button and last channel entry is stored in nonvolatile memory. Agility allows maximum flexibility in altering system channel line-ups and instant fixed channel replacement. The synthesizers are crystal referenced and microcomputer controlled for accuracy and stability. With the RS232 option the modulator can be remotely controlled via PC and modem.
This series is manufactured in NTSC, PAL and SECAMstandards.
