It’s the heart and soul of your operation. Day in, day out delivering quality video, audio and data to your customers. There’s no bigger investment in your system than your headend electronics. Now think about what goes into a great headend: high-quality electronic equipment with state of the art design and engineering, equipment that you’re proud to see on the headend rack. Sleek and stylish on the outside. Powerful and reliable on the inside. Versatile and practical all around. Agile to meet your changing needs and able to reach your bandwidth requirements with capacity to grow. Specs to make you smile and performance to make your customers sit up and notice. Well, how about that: We’ve just described the Macom Professional Series headend products.

PM45-UHF : 45 dB IF-Loop Modulator

Features

• 125 Channel Frequency Range 54~806 MHz (CATV 2~13, A1~A5, A~222, 89~125, UHF 14~69)
• SAW filtered for superior adjacent channel performance enables drop-in channel expansion
• 45 dBmV minimum output
• Composite audio-video IF loop provides compatibility with encoders, ghost cancelers and video override applications
• BTSC stereo compatible pre-emphasis disable switch provides pass-through for stereo signals
• Audio and video over-modulation indicators for quick performance reference
• 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

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-offband 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.
