The
PDI-55-SFS is a fixed channel, PLL controlled, video and audio modulator
with SAW filtering. It is available for any cable channel between
2 through 134. Itsr video dynamic range insures 87.5% modulation
depth over a wide video input range. The vestigial sideband selectivity
allows maintenance free adjacent channel configuration. An efficient
power supply enables cool and stable operation. The PDI-55-SFS offers
high performance, low cost and compact design with a 2 year warranty.
