MMA860: Universal Chassis Mini Agile Modulator 

Previously known as Pico Macom MMA860 

 

Features

 

  • 135-channel range 54 MHz to 860 MHz (CATV 2-135), TV: CH 2 to CH 78 (54 MHz to 860 MHz)

  • > 45 dBmV min. adjustable output for optimum carrier-to- noise performance

  • Compatible with most manufacturers mini-modulator chassis

  • State-of-the-art digital Phase Locked-Loop (PLL) design guarantees precise frequency locking for solid drift-free operation

  • Microprocessor control enables quick digital pushbutton channel selection for ease of installation, configuration, and improved system uptime 

 

  • SAW (Surface Acoustic Wave) filtered for superior adjacent channel performance enables drop-in channel expansion

  • In band carrier-to-noise ratio > 65 dB ensures superior picture quality

  • Automatic selection of aeronautical offsets (12.5 kHz, 25 kHz) for trouble-free configuration

  • Front panel access controls for easy set-up
