Agile Demodulator

TAM 860

Catvision Agile Modulator TAM 860 is a professional adjacent channel modulator, specifically designed for use in CATV headend systems.

The TAM 860 is a necessity for every headend system as a backup in case of breakdown of regular modulators. This modulator can be tuned to any channel in the 47~860 MHz frequency range. In case of supply interruption these agile modulators remain tuned to the last channel.

Special SAW filter circuit is incorporated for superior signal quality with high adjacent channel rejection suitable for headend application. Digitally-controlled PLL technique ensures high frequency stability.
