The Blonder Tongue CATV Modulator SAW Filtering Channel 52from Blonder Tongue CATV Modulator SAW Filtering Channel 52is 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.

[-90 dBc] Had a 60 cycle hum in my audio/video system and narrowed It down to the Blu-Ray player and cable box were causing a ground loop. Installed the Jensen ISO-Max VRD-1FF on the cable line before the box and it worked - no more hum. Much thanks to Jensen and B&H. 5
