PDI-60AD Demodulator
PDI-60AD Demodulator
Description Features Specifications  
DESCRIPTION
The PDI-60AD is a frequency agile, television demodulator. Input tuning covers the range of 54 to 811MHz with the ability to properly receive CATV channels already offset 12.5 or 25 kHz as in node operation and provides baseband audio and video outputs for any channel in that spectrum. Its user friendly channel selection is by simple front panel push button with non volatile memory. Rock solid PLL tuning by advanced microprocessor insures precise UHF/VHF or CATV (STD/HRC) channel access. AGC circuitry adjusts for input signal variations. The unit exhibits excellent video and adjacent channel performance. Broadband multiplex audio output permits use in BTSC stereo applications. The demodulator is 1 3/4' in height and is designed for 19' rack mounting. Optional left and right decoded stereo outputs (PDI-60AD-ST). Another available option is decoded SAP output (PDI-60AD-SP). The PDI-60AD can also have BOTH options if so desired (PDI-60AD-ST-SP)!
