Product Description

MIC-9902 series CATV RF 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

1. MIC-9902 is 870MHz fixed channel modulator.

2. With high quality SAW filter for slight jamming.

3. Video modulation depth, audio modulation depth, A/V ratio and RF output level are all modulated on front panel.

4. LED display,19"1U case.
