BAVM-860SAW
Channelized Audio/Video Modulators
The Blonder Tongue BAVM-860SAW is an
economical commercial quality TV
modulator. It provides a +55 dBmV RF
output on any specified CATV channel from
2 to 135 (54 to 860 MHz). HRC and IRC
frequency plans are also available. The
BAVM-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 BAVM860SAW features 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 the
BAVM-860SAW compatible with any outboard stereo generator that provides a
composite baseband output. A -30 dB
output test point and all user controls are
provided on the front panel.
