Pico Macom MMA860S Mini Stereo Agile Modulator

The MMA860S is a professional grade microprocessor-controlled stereo agile audio/video mini modulator. This modulator accepts any audio-video baseband television signal and provides a 45dBmV minimum output on CATV channels 2 to 135 (54-860 MHz). Channel selection is easily accomplished via channel up/down buttons located on the front panel. Up to 12 or 16 units can be installed "mix-and-match" in Pico Macom’s MPC-12, MPC-12C, MPC-12R chassis with MPCM45 mini-modulators or MPCD mini-demodulators. Its unique design enables it to be installed in other manufacturers’ mini-mod chassis. The unit’s tracking filter technology and double-heterodyne conversion ensures accurate and spurious-free output. The MMA860S uses SAW filtering in conjunction with FCC group delay correction circuitry to provide superior adjacent channel selectivity. The unit’s PLL circuitry in conjunction with the non-volatile memory contained in the microprocessor ensures easy and reliable channel selection and restoration. The MMA860S modulator is shipped with all internal adjustments preset. Pico Macom backs up this product with its industry leading 5-year limited warranty.
