The CAM-60 Series are professional quality, channelized, heterodyne audio/video modulators. These units provide audio and video modulated RF carrier output on any SUB, VHF, UHF, or CATV channel (7 to 450 MHz and 50 to 860 MHz). Any standard audio/video source can be used, such as satellite receivers, television cameras, video tape recorders, or television demodulators. These modulators feature a frequency agile output converter followed by a single channel removable output filter providing +60 dBmV output. This design configuration permits easy channel changes in the filed by simply replacing the output filter module and setting the output converts dip switches to the new channel. The CAM-60 Series takes baseband audio and video and modulates these signals onto the desired output channel (each modulator has separate audio and video inputs). The heterodyne conversion process used in the CAM-60 Series employs a crystal referenced, PLL synthesized local oscillator, with a 12.5 kHz tuning increment. This guarantees rock solid, no-drift output for the life of the modulator. A custom SAW filter is employed to provide true vestigial sideband selectivity with built-in FCC group delay pre-distortion. The CAM-60 Series meets FCC Docket 21006 aeronautical frequency offset requirements (±5 kHz video carrier accuracy) and accepts standard polarity (sync negative) video in the range of 0.7 to 2.8 V p-p. A 4.5 MHz audio input is provided, which preserves the stereo audio available from most satellite receivers and demodulators. A rear panel switch allows selection of either baseband audio or 4.5 MHz audio.
