VMM860AG and other compatible
modular units
ensures optimum vestigial selectivity for
adjacent channel headends. An optional FCC
predistortion SAW response is also available for
the VMM860AG.
The modulator is designed to accept any
standard audio/video source such as NTSC
video and audio baseband signals from a
satellite receiver, TV camera, videotape
recorder, TV demodulator, or similar signal
source.
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.
Field-defeatable audio pre-emphasis, by means
of a rear panel switch, allows transmission of
BTSC encoded baseband stereo audio signals
when used with the Drake MMTS20 stereo
encoder.
