Digital Tv Modulators

Product Description

This modulator is a professional grade microprocessor controlled phase-locked loop synthesized single channel audio-video modulator.

This modulator is used in more heavily channel-loaded systems and where cost effective expansion up to **0MHz is desired and greater frequency stability and higher spurious free adjacent channel performance is required. Its phase locked loop frequency control, and superior Triple SAW filtering enhances stability, minimizes adjacent channel interference and assures accurate and spurious free output. Superior out-of-band carrier-to-noise performance is achieved through band-pass filtering at the output amplifier. The modulator is shipped with all internal adjustments present
