Blonder Tongue CATV Channelized Audio/Video Modulator with SAW Filtering (Channel 11)

Blonder Tongue BAVM-860SAW-860-11 Overview

The CATV Channelized Audio/Video Modulator, Channel 11, from Blonder Tongue is an all-solid-state audio/video modulator that provides a modulated visual and aural RF carrier output on one specific CATV channel. The unit modulates the audio and video inputs and provides the requested RF CATV channel output for use in a CATV, MATV or SMATV system. The modulator accepts standard (sync negative) polarity video at a 0.7-2.5V peak to peak level from sources such as a TV camera, video tape recorder, TV demodulator or satellite receiver.

The modulator features a +55dBmV RF output level, and an IF SAW filtering for adjacent channel operation. All aeronautical channels are offset positive with a tolerance of ±5kHz as required by FCC 21006. All level controls are located on the front panel. The RF level control provides up to +55dBmV output. The video modulator control sets the depth of modulation for 87.5% over an input video level range from 0.7VP/p to 2.5VP/p. An audio modulation control permits adjustment for ±25kHz peak deviation of the aural carrier.

Meets FCC docket 21006 aeronautical frequency offset requirements
Fully compatible with BTSC encoded stereo audio
Front panel accessible level controls for easy set-up and adjustments
