Measuring only 3" x 4.5" x 1", the ATD is a compact Agile Tuner Demodulator with non-volatile channel memory in the event of power interruption. Incorporating a commercial quality tuner demodulator, the ATD can be used in cable television headends for demodulator-modulator signal processing applications or for other headend demodulator applications. The ATD also makes a great spare Demodulator for Cable Technicians to have on hand in case one fails, or can be used as a portable tuner for LCD or Plasma displays that don't have a tuner built-in. The ATD features an On-Screen display and is capable of tuning CATV channels 2 -125 and Off-Air (VHF/UHF) Channels 2-69. The ATD consumes only 2.25 watts of power, and is powered by a 9 V DC adaptor or a battery. Multiple ATD's can be Rack mounted on one Panel, or can be mounted directly on any surface using an optional mounting bracket.
