Universal-Chassis Agile A/V Mini-Modulator
MPCMA
Universal-Chassis Agile A/V Mini-Modulator
The MPCMA is a professional grade microprocessor-controlled agile audio/video mini-mod-
ulator. This modulator accepts any audio-video baseband television signal and provides a
45dBmV minimum output on CATV channels 2 to 135 (54-860 MHz) while accommodating
HRC and IRC offset frequencies. Channel selection is easily accomplished via channel
up/down buttons located on the front panel while built-in RF muting circuitry prevents inter-
ference during online channel reassignment. This MPCMA features >-90dB out-of-band car-
rier-to-noise ratio, allowing virtually unlimited numbers of MPCMA's to be combined in a
system without the need for external bandpass filtering. Up to 12 or 16 units can be installed
"mix-and-match" in Pico Macom's MPC12, MPS12, MPC12R or MPC16 chassis with
MPSM45 and 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 MPCMA 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 MPCMA modulator is shipped with all internal adjustments
preset. Pico Macom backs up this product with its industry leading 5-year limited warranty.
