Product Description

870 MHz CATV Analog Fixed Channel Modulator CATV Channel Modulator 

Fixed Channel Modulator (DT-FCM-9902) fixed channel modulator is an economical headend equipment for the modulation of video and sound signals. It adopts the advanced modulation circuit and PLL (phase-locked loop) technique to ensure high frequency stability and good out-of-band rejection. It is widely used in the medium or small sized CATV system and the safety defence monitoring system.

★Features

 

⊙LED display,19″1U case.
⊙Operation bandwidth is 870MHz.
⊙With high quality SAW filter for slight jamming.
⊙Video modulation depth,audio modulation depth and RF output level are all modulated on front panel.
