MPCMA
Descriptions
The
MPCMA
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) 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 interference during online channel reassignment. This
MPCMA
features >-90dB
out-of-band carrier-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.
