The ChannelPlus "D" Series are digitally-tuned video modulators that convert any
baseband video and audio signal toa user-selected UHF, Ultraband CATV, Japan or
PAL channel. An internal temperature-compensated quartz crystal reference
oscillator and PLL circuitry ensure drift-free performance. The user selects the
output frequency (channel) using the "up" and "down" buttons while observing the
digital display on the front panel. Any TV connected to the output via coax can
receive the signals,when the TVis tuned to the proper channel.
