MMA860
Universal-Chassis Mini-Agile Modulator
The MMA860 is a professional grade microprocessor-controlled 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, MPS-12, 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 ensure accurate and spurious-free output.
The MMA860 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 MMA860 modulator is shipped with all internal adjustments
preset. Pico Macom backs up this product with its industry leading 5-year limited warranty.
