TP300 Processor
The TP300 contains the latest in television electronics, including synthesized crystal- referenced phase-locked-loop oscillators, microprocessor control, SAW-filtered IF and hybrid amplifiers. In addition to these features, it contains automatic input offset programming to remove input offset programming to remove input offsets inherent to off-air channels (0, ±10 KHz), cable standard channels (0, +12.5 KHz, +25KHz) and cable HRC channels (0.3 KHz master oscillator offset).
