Adjacent Channel Modulator

ACM 345


Catvision Cable TV Modulators ACM 345 incorporate high VSB attenuation that ensure adjacent channel operation. These are suitable for small networks. They use crystal-based oscillator for excellent frequency stability and good picture & sound quality.



  • RF output of 105 dBµV (ACM-345)
  • Fixed channel from 47 ~ 300 MHz (36 ch.)
  • Adjacent channel rejection >65 dBc
  • Standard 19 inch rack mount type
  • Crystal oscillator for stable frequency
  • Low out-of-band noise for high C/N
  • AC socket for loop-through AC power
