Pico Macom PFAD900CS User manual

PFAD900CS
The Pico Macom PFAD900CS is a frequency agile professional re-broadcast
grade, microprocessor controlled CATV demodulator. Its phase-locked-loop fre-
quency control, envelope signal detection, and superior SAW filtering minimize
adjacent channel interference and assure accurate and spurious free perform-
ance.The unit accepts any NTSC television signal in the 54-806MHz frequency
range converting it to baseband video and audio, while maintaining over 60dB
S/N ratio. IRC or HRC offsets can be activated via push-button switches on the
front panel.The unit’s PLL circuitry in conjunction with the non-volatile memory
contained in the microprocessor ensures easy and reliable channel selection and
restoration.The PFAD900CS provides three additional outputs: (1) an IF output
to monitor tuner status and use in encoder, ghost cancelling, and video override
applications; (2) a 4.5MHz sub-carrier output; and (3) a broadband multiplex
(MPX) output for high quality BTSC stereo.The PFAD900CS demodulator is
shipped with all internal adjustments preset. Pico Macom backs up this product
with its industry leading 5-year limited warranty.
