Para-Broadcasting Smart Agile Modulator Introduction It is equipped with the latest CATV electronic technology, including crystals simultaneous PLL vibration circuit, SAW IF circuit, hybrid amplifying circuit and CPU control. It is high quality, vestigial sideband equipment synthesized with audio and video carriers. It uses audio and video baseband signals coming video recorder, video camera, or similar equipments as signal source. Its receiving video input level is 0.5Vp-p~1.5Vp-p. Working parameters and status are displayed by LCD on front panel, such as output channel, output frequency, A/V ratio, video modulation depth, audio deviation, audio carrier, output level, test signal. The parameters can be ed with the buttons on the panel. The high quality SAW filter removes adjacent disturbance. The above characteristics are carefully designed into very low intermodulation level to allow adjacent operation within 860MHz. Features With complete CPU control, it has self-check monitoring function. Agile output frequency (47~866025MHz), stepping by 0.25MHz. Output level up to 116dB. All the technical parameters are adjustable. Audio carrier 4.5/5.5/6.0/6.5MHz is able.
