PCM55SAW is a professional grade microprocessor controlled phase-locked loop synthesized channelized-agile audio-video modulator

The Pico Macom PCM55SAW is a professional grade microprocessor controlled phase-locked loop synthesized channelized-agile audio-video modulator. The PCM55SAW provides a full 55dBmV minimum output from sub-band channels T7 through T13, and CATV channels 2 to 78 including channels 95 to 99 while accommodating HRC and IRC offset frequencies (5.75-550MHz). The unit is lab re-tunable within band via internal dip-switch channel selection and minimum output filter retuning. This modulator is used in more heavily channel-loaded systems and where cost effective expansion up to 550MHz is desired. Its phaselocked loop frequency control, and superior SAW filtering enhances stability, minimizes adjacent channel interference and assures accurate and spurious free output. The modulator is equipped with a pre-emphasis disable switch which enables pass-through of high-fidelity BTSC stereo signals where available.

Superior out-of-band carrier-to-noise performance is achieved through bandpass filtering at the output amplifier. The modulator is shipped with all internal adjustments preset. FCC Docket 21006 offsets are standard. Pico Macom backs up this product with its industry leading 5-year limited warranty.

Full 55dBmV output for optimum carrier-to-noise performance

In-band carrier-to-noise ratio >62dB ensures superior picture quality

BTSC Stereo Compatible pre-emphasis disable switch provides pass-through for stereo signals

Highly accurate DIP switch controlled digital phase-locked loop

(PLL) design guarantees precise frequency locking for solid driftfree operation

SAW filtered IF for superior adjacent channel performance enables drop-in channel expansion Easy lab retuning of output filter for reduced inventory of spares and less down time Front panel controls and test point enable easy setup and monitoring IRC and HRC offset available for frequency settings in systems using offset channels

Auxiliary AC outlet for convenience

PLM860SAW  $229 860MHz Channelized-Agile PLL SAW Filtered A/V Modulator

The PLM860SAW modulator features a digital phase-locked loop (PLL) and saw filter for superior adjacent channel performance and drift-free channel stability. This professional grade modulator maintains a full 55dBmV output on channels 23 to 135 while accommodating HRC and IRC offset frequencies (216-860 MHz). The PLM860SAW is a very cost effective method to expand an existing cable system beyond 300MHz. The PLM860SAW was designed to extend channel capacity of systems using PCM55, PLM55, or PCM55SAW modulators.

Its SAW filter provides superior sideband filtering, adjacent channel compatibility, and spurious free output. High quality modulation and RF level control potentiometers assure years of reliable operation. Easy lab retuning enables inventory savings and less down time. The PLM860SAW is shipped with all internal adjustments preset. FCC Docket 21006 offsets are standard. Pico Macom backs up this product with its industry leading 5-year limited warranty.

113-Channel Range 216-860 MHz (CATV 23-135)

DIP switch controlled digital phase-locked loop for solid driftfree output on any channel

SAW filtered for superior adjacent channel performance enables drop-in channel expansion

55dBmV output for optimum carrier-to-noise performance

In-band carrier-to-noise ratio >62 dB provides superior picture quality

Front panel test point for easy RF level system monitoring

IRC and HRC offset available for frequency settings in systems using offset channels

Auxiliary AC outlet for convenience

Optional PAL format channels available

PM45 806MHz Channelized-Agile PLL SAW-Filtered A/V Modulator with 125-Channel Range 54-806 MHz (CATV 2-125) and 45dBmV adjustable output for optimum carrier-to-noise performance

The Pico Macom PM45 is a professional grade phase-locked loop synthesized channelized-agile audio-video modulator. This modulator provides 45dBmV minimum output on CATV channels 2 to 125 (54-806 MHz) while accommodating HRC and IRC offset frequencies. The PM45 features a composite audio-video IF loop, which provides compatiblility with encoders, ghost cancellers, and video-override applications. The unit can be reconfigured to any output channel by qualified service centers. This cost effective modulator can be used to expand systems using PCM55, PCM555AW and PLM55 modulators beyond 300MHz, where the expansion does not require modulators with higher output levels. The PM45 provides the greater frequency stability and higher adjacent channel performance required in such expansions. The modulator is equipped with a pre-emphasis disable switch which enables pass-through of high-fidelity BTSC stereo signals where available. Its phase-locked loop frequency control, and superior SAW filtering enhances stability, minimizes adjacent channel interference and assures accurate and spurious free output. Superior out-ofband carrier-to-noise performance is achieved through band-pass filtering at the output amplifier. The PM45 is shipped with all internal adjustments preset. FCC Docket 21006 offsets are standard. Pico Macom backs up this product with its industry leading 5-year warranty.
