The MM653 frequency agile modulator from Master Video incorporates a microprocessor with nonvolatile memory, elimenates front panel push buttons or DIP switches to control the tunable SAW filtered output from 50 to 650 MHz on any broadcast or CATV channel. 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 micro-computer controlled for accuracy and stability. Status read and Channel set can be done remotely from anywhere with the RS232 optional PC module and software.
This series is manufactured in NTSC, PAL and SECAMstandards.
