MPCM45ULTRA2 : Mini-Modulator

Features

125 Channel Frequency Range 54~806 MHz (CATV 2~13, A1~A5, A~222, 89~125, UHF 14~69)
SAW (surface acoustic wave) filtered for superior adjacent channel performance enables drop-in channel expansion
45 dBmV minimum output for a 66 dB in-band carrier to noise ratio provides superior picture quality
BTSC stereo compatible pre-emphasis disable switch provides pass-through for stereo signals
Front panel access to controls enables easy setup
IRC and HRC offset available for frequency settings in systems using offset channels
Compatible with most manufacturers? mini-modulator chassis
Optional PAL format channels available

The Pico Macom MPCM45 is a professional grade high-performance CATV mini-modulator. This modulator accepts any audio-video baseband television signal and provides a 45dBmV minimum output on CATV channels 2 to 125 (54-806 MHz) while accommodating HRC and IRC offset frequencies. The unit can be reconfigured to any output channel within band by qualified service centers. Up to 12 or 16 units can be installed "mix-andmatch" in Pico Macom's MPC12, MPS12, MPC12R or MPC16 chassis with MPCMA agile mini-modulators or MPCD mini-demodulators. Its universal design enables it to be installed in other manufacturers? mini-mod chassis. The unit?s phase-locked loop (PLL) circuitry and unique multi-stage output bandpass filtering ensure accurate and spuriousfree output. In addition, the MPCM45 uses SAW filtering with FCC group delay correction circuitry to provide superior adjacent channel selectivity. The MPCM45 modulator is shipped with all internal adjustments preset. Pico Macom backs up this product with its industry leading 5-year limited warranty.
