Passive Devices PDI-60AFP is a professional quality, user friendly, high performance TV signal processor designed primarily for CATV headend operation. Rock solid PLL controlled tuning by advanced microprocessor insures precise UHF, VHF or CATV (STD-HRC) channel access. Careful design of the input achieves a wide dynamic range and a very low noise figure. Input tuning covers the range of 54 to 860MHz with the ability to properly receive CATV channels already offset 12.5 or 25kHz as in node operation. The fixed channel output ranges from 54 to 860MHz plus sub channels T-7 through T-13 and is controlled by another PLL circuit. Necessary 12.5 (or 25kHz) offsets are factory set depending on the output frequency. The selected input channel has non-volatile memory that restores the channel automatically in the event of a power failure. SAW filtering guarantees broadcast quality pictures. A standby oscillator provides a CW video carrier level for system pilot AGC control if the input drops below a useable level. $756.00
