DRAKE VMM860AG

DRAKE VMM860AG is a high quality, vestigial sideband unit with synthesized visual and aural carriers. The frequency agile VMM860AG allows front panel pushwheel switch selection of standard CATV channels 2 through 135, or VHF/UHF TV channels 2 through 69. Aeronautical channels are offset positive with a tolerance of ±5 kHz as required by FCC rules. The modulator is designed to accept standard (negative sync) polarity video at nominal 1 V p-p level. All level controls are located on the front panel for ease of operation. Output level is +45 dBmV and is adjustable over a 10 dB range. The heterodyne conversion system, in conjunction with the use of a SAW filter, ensures optimum vestigial selectivity for adjacent channel headends. An optional FCC predistortion SAW response is also available for the VMM860AG.
