    BAVM-860-SAW-2 - Overview

    The Blonder Tongue BAVM-860SAW is an economical commercial quality TV modulator. It provides a +55 dBmV RFoutput on any specified CATV channel from 2 to 135 (54 to 860 MHz). HRC and IRC frequency plans are also available. TheBAVM-860SAW is ideal for placing A/V program sources such as satellite receivers,VCR's, DVD's, cameras or TV demodulators onto standard 6 MHz NTSC TV channels for broadband distribution. The BAVM-860SAWfeatures IF SAW filtering with built-in FCC group delay pre-distortion assuring excellent adjacent channel performance and color operation. The modulator complies with FCC 21006 with +/- 5 KHz visual carrier stability and required frequency offsets on all aeronautical channels. For BTSC stereo applications, a field-defeatable audio preemphasis network is provided making theBAVM-860SAW compatible with any outboard stereo generator that provides a composite baseband output. A -30 dBoutput test point and all user controls are provided on the front panel.
